Whereas monoculture studies performed at zone 3 (3-6%) mimicked the results obtained at zone 1, both co-culture and LAMPS models performed at low oxygen showed distinct differences compared to studies performed at zone 1 oxygen tension. While the constitutive growth advantage for ESR1 mutants remained unaffected, the enhanced E2-dependent growth for the Y537S mutation and the E2-dependent growth for WT expressing cells were lost. Overall, these results demonstrate the importance of oxygen tension in regulating specific growth phenotypes conferred by ESR1 mutants."

Oxygen tension: 5 ul/hr.\r\n\r\nThe goal was to examine the effects of changes in oxygen tension on growth phenotypes conferred by ESR1 mutant-expressing cells in the LAMPS models. Whereas monoculture studies performed at zone 3 (3-6%) mimicked the results obtained at zone 1, both co-culture and LAMPS models performed at low oxygen showed distinct differences compared to studies performed at zone 1 oxygen tension. While the constitutive growth advantage for ESR1 mutants remained unaffected, the enhanced E2-dependent growth for the Y537S mutation and the E2-dependent growth for WT expressing cells were lost. Overall, these results demonstrate the importance of oxygen tension in regulating specific growth phenotypes conferred by ESR1 mutants."

The model system used for these Tier1 studies is just the tissue prepared by Columbia. The tissues were constructed in the laboratories of Dr. Angela Christiano. Tissue punches were prepared by her laboratory, placed into a gel with the living dermal side in the gel and the air-exposed surface kept dry. The tissues were shipped to the Texas A&M Institute of Biosciences and Technology overnight with the earliest delivery available via Federal Express. The purpose of the Tier1 studies was to 1) demonstrate that viable tissues could be shipped from the tissue developer’s laboratory in New York to the testing center in Houston and that they would arrive alive and suitable for testing and 2) repeat the testing of drugs that had also been tested by the tissue developer’s laboratory as a measure of reproducibility."

The overall study plan is a comparison of normal human jejunal-derived enteroids from the laboratory of Dr. Mary Estes at the Baylor College of Medicine with the colorectal adenocarcinoma derived Caco-2 cell line (HTB-37™) obtained from the ATCC that is considered an industry standard for drug permeability studies. The model system used for these studies is a two-dimensional transwell into which the enteroids and Caco2 cells are seeded. Over a period of 7 days in differentiation media the jejunal enteroids form a confluent monolayer with defined apical and basolateral surfaces, develop tight junctions and form a functional barrier. Likewise, over a period of 21 days differentiation after plating, the Caco-2 cells also form a confluent monolayer with defined apical and basolateral surfaces, develop tight junctions and form a functional barrier.\r\n\r\nTier-2 testing focuses on extending the use of the microphysiological systems. The testing center greatly expanded the number of drugs being tested using both the enteroid and Caco-2 model system. A set of 12 drugs with well-characterized Caco-2 permeability (Optimization of the Caco-2 permeability assay to screen drug compounds for intestinal absorption and efflux. Press B. Methods Mol Biol. 2011;763:139-54. doi: 10.1007/978-1-61779-191-8_9. PMID:21874449) were used to establish a permeability standard curve. The drugs were then tested in the enteroid model to determine whether a similar curve could be constructed. These standard curves were then used to allow for the testing of an additional 13 drugs recommended for testing by the IQ Consortium. As with Tier-1 testing, the development and maintenance of barrier integrity were measured using transepithelial electrical resistance (TEER). The maintenance of barrier function during drug treatment was determined using both TEER (before and after drug exposure) and by the movement of 10kDa-FITC-labeled dextran from the comparment containing the drug to the receiving side. Two drug concentrations were tested, 10µM and 1µM for all drugs used in the Tier-2 studies. For permeability studies, the drugs were added on the apical side of the cell barrier. After 90 minutes at 37ºC in the cell culture incubator, aliquots of the media were removed from both the apical and basolateral compartments of the transwell device. The amount of 10kDa-FITC-labeled dextran in the media was quantified using a fluorescent plate reader. The viability of the cells in the transwells after drug treatment was measured using CellTiter Glo from Promega. The drug levels in the media samples were quantified using LC/MS. Additional studies were performed to measure drug efflux pathways by adding drugs to the basolateral side of the transwell and then quantifying the amount of drug in media samples taken from both the basolateral and apical sides of the device."

In addition to testing the transfer and reproducibility of the human jejunal enteroid model, the tissue chip testing center is using the Caco-2 model as a comparator. For these studies, the development and maintenance of barrier integrity were measured using transepithelial electrical resistance (TEER).

Also during Tier-1 testing, the testing center examined the concentration dependence of drug-induced cytotoxicity in the Caco-2 cells grown as a two-dimensional monolayer of cells in a standard tissue culture plate. Similar cytotoxicity studies were performed using the enteroids plated on collagen-coated wells. Because of the short time to differentiate the enteroids, 5 days compared with 21 days for Caco2 cells, drug cytotoxicity was tested in both undifferentiated enteroids and enteroids grown for 5-7 days in differentiation media."

"description": "TAMU/IBT Tier-2 Human Skin. The overall study plan is a comparison of human skin constructs from the laboratory of Dr. Angela Christiano at Columbia University with the Organisation for Economic Co-operation and Development (OECD) and industry-recognized standard, Epi-Derm commercially available from MatTek Corporation. The model system used for these Tier2 studies is just the tissue prepared by Columbia. The tissues were constructed in the laboratories of Dr. Angela Christiano. Tissue punches were prepared by her laboratory, placed into a gel with the living dermal side in the gel and the air-exposed surface kept dry. The tissues were shipped to the Texas A&M Institute of Biosciences and Technology overnight with the earliest delivery possible via Federal Express. The Tier2 studies are focused on the use of the skin tissues as a model for assessing the irritation or corrosive properties of chemicals. The industry standard has always been an animal model. It has long been desired that an in vitro alternative to the use of animals be found. The OECD has evaluated many models and the EpiDerm model available from MatTek Corporation has been recognized as an alternative. The purpose of the Tier2 studies was to compare the Columbia skin construct with the MatTek EpiDerm and EpiDerm-FT models for their ability to predict 1) whether or not a compound acts as a skin irritant and 2) whether or not a compound acts as a skin corrosive agent. For these studies, six compounds were selected that have known properties and that have been evaluated in many in vitro model systems. \r\n\r\nThe compounds tested were diethyl phthalate (CAS no. 84-66-2) a known non-irritant, 1-bromohexane (CAS no. 111-25-1) a known skin irritant, 1,9-decadiene (CAS no. 1647-16-1) a known non-corrosive compound that can be a skin irritant, isostearic acid (CAS no. 30399-84-9) a known non-corrosive compound, phosphorous tribromide (CAS no. 7789-60-8) a known skin corrosive and hydrochloric acid (CAS no. 7647-01-0) also a known skin corrosive compound.\r\n\r\nTissue viability after compound exposure is used by the models to determine whether or not a compound is an irritant or corrosive. The post-assay viability was measured by using PrestoBlue. Three aliquots were removed from each tissue sample and read in a fluorescent plate reader. These RFU values were reported to the database. The mean of the three replicates was then normalized to the water-treated negative controls. These values are reported in the MPD database as ‘% Control’ and are used by the models to predict reactivity. The corrosion test used 8N KOH as a positive control and the irritation test used 5% SDS as a positive control. The predictions of irritant, corrosive or not are reported in the MPS database as either a value of 0 meaning no effect or a value 1 meaning the compound was predicted by the model to be an irritant or corrosive depending on the assay being conducted."

"description": "March 7th, 2017 TAMU Blood-Brain Barrier (NVU) study. The purpose of this study was to demonstrate the creation of a functional blood-brain barrier (BBB) using the Vanderbilt University Neurovascular Unit (NVU). Barrier formation was determined using daily measurements of FITC-labeled 10kDa dextran. Each NVU device has media flowing through the device at a constant 2uL/min from two inlet ports supplied by syringe pump. The vascular side of the device was continuously perfused with EBM-2 media containing 1mg/mL FITC-dextran. The brain side compartment of the NVU was perfused with growth medium without FITC-dextran. Effluents were collected over a one hour period each day from both the vascular and brain sides of the device. The amount of FITC-dextran was determined by measuring the fluorescence in a 50uL aliquot of each effluent. As the endothelial cells proliferate and form tight junctions creating the BBB, one observed a decrease in the amount of FITC-dextran appearing in the effluent collected from the brain side of the NVU. All of the NVUs demonstrated some degree of FITC-dextran exclusion from the brain side effluent with increasing time in culture. Of the nine NVUs started for this study, four remained operational throughout the study period and exhibited barrier formation. After 24days in culture the barrier function on the four remaining NVUs was testing using Terfenadine and Fexofenadine. Terfenadine, a drug with know CNS effects, was expected to cross the NVU's BBB and be detectable in the brain side effluent. Fexofenadine, a drug without CNS effects and the active metabolite of Tefenadine, was expected to remain only in the vascular side effluent. Drugs were introduced from the vascular side in growth media that also contained 1mg/mL FITC-dextran. NVUs were exposed to drug for 2hr during which effluent was collected from both the vascular and brain side compartments. This was a dose escalation study where the first dose tested was 0.01uM. After 2hr, flow was stopped, new syringes were attached to the vascular side inlet of the NVU with the next higher concentration of drug. A total of 4 concentrations were tested (0.01, 0.1, 1 and 10uM) over a single 8hr period. A single NVU was included as a vehicle control. Both Terfenadine and Fexofenadine were prepared as 50mM stocks in DMSO. The drugs were serially diluted in growth media for testing and the vehicle control was tested using DMSO equivalent to the 10uM drug (a 1:5000 diultion). Effluent samples were tested for the presence of FITC-dextran and lactate dehydrogenase release as surrogate markers for compromised blood-brain barrier integrity and cellular viability, respectively."

Whereas monoculture studies performed at zone 3 (3-6%) mimicked the results obtained at zone 1, both co-culture and LAMPS models performed at low oxygen showed distinct differences compared to studies performed at zone 1 oxygen tension. While the constitutive growth advantage for ESR1 mutants remained unaffected, the enhanced E2-dependent growth for the Y537S mutation and the E2-dependent growth for WT expressing cells were lost.

At each timepoint, phase contrast images were captured (10FPS), and analyzed using the MotionGUI script in Matlab (provided by UC-Berkeley). The outputs of this program were beat rate (BPM), time interval (s, duration between contraction and relaxation), contraction velocity (px/s), and relaxation velocity (px/s). As an additional endpoint, cells were treated with a calcium sensitive dye on day 11, and calcium flux was measured as beats/min.\r\n\r\nNote: Cells stopped physically beating at around day 7 (day 3 of treatment), but calcium flux was still detectable at endpoint on day 11."

In this study, 55 chips were seeded with iPSC-derived cardiomyocytes purchased from CDI (iCell Cardiomyocytes, lot #1293677) in a central growth chamber. Cells were cultured over 4 days in the chip prior to testing with reference compounds. Cultures were treated with either vehicle (n=9, 0.1% DMSO), atenolol (0.01µM, n=4; 0.1µM, n=3; 1µM, n=3; 10µM, n=3), sorafenib (0.1µM, n=4; 1µM, n=3; 10µM, n=3; 100µM, n=3) or carbamazepine (0.1, 1, 10, 100µM, n=5 each) over a 1 week period. At each timepoint (baseline, 5 hours, and daily for days 1-7), phase contrast images were captured (10FPS), and analyzed using the MotionGUI script in Matlab (provided by UC-Berkeley). The outputs of this program were beat rate (BPM), time interval (s, duration between contraction and relaxation), contraction velocity (px/s), and relaxation velocity (px/s). Immunohistochemistry was difficult in this chip, so images are displayed as phase contrast only. \r\nIt should be noted that while CDI cells performed well for the first few days of treatment, after 3-4 days many chips stopped beating, even the vehicle controls. This was also noted in the 2D side-by-side comparison-- while cells were still viable and fluxing calcium in 2D, they were not physically beating, therefore the motion tracking program did not work for these later days of culture."

The overall study plan is an evaluation of the acute and chronic effects of drugs on the ability of skeletal muscle fiber microphysiological systems to respond to electrical stimulation with either a twitch or tetanus response. The tissues were constructed using cells isolated from patients and provided by Dr. George Truskey’s laboratory at Duke University. In addition to the frames, Dr. Truskey’s group provided all of the frames that had ecoflex bands attached. The PDMS plates and molds were made by Dr. Arum Han’s research group at Texas A&M in College Station. The components were assembled, the cells propagated and plated into the devices, and drug treated and tested at the Texas A&M Institute of Biosciences and Technology in Houston. The purpose of the Tier2 studies was to extend the testing of the MPS beyond that of the previous work by the tissue developer. In this instance the TAMU/IBT testing center tested four additional drugs for acute and chronic effects. The drugs were Sunitinib, Nelarabine, Metformin, and Erlotinib. These drugs are suspected of causing rhabdomyolysis a side effect of drug treatment resulting in extreme muscle fatigue or nonresponsiveness."

Cultures were taken out over 16 days under static airflow conditions, then moved to an air exposure chamber, where they were exposed to either 0, 5, or 10mL/min clean air-flow for 5 hours, then moved back to normal culturing conditions and allowed to recover overnight until endpoint on day 17. At endpoint, chips were tested for Viability and LDH release, as well as imaging (b-tubulin, ZO-1, cell height, membrane coverage)."

After that, iHep plating media was added to the perfusion channel. Perfusion was initiated immediately by rocking. On Day 5, HMEC-1 cells were loaded into the perfusion channel, and allowed 1 hour to attach with the plate on its side. Then, iHep maintenance media or iHep/HMEC-1 mixed media was added to the perfusion channel. Media was collected and refreshed everyday. The plate was incubated at 37°C with perfusion by rocking. No test articles were treated. On Day 21, half the wells were treated with Calcein/Hoechst/Propidum Iodide (for cell viability) and 4% PFA (fixed for ICC). The assays for albumin, BUN, LDH, and AFP were conducted with collected media."

"description": "This is a re-run of “Kidney Study 17”, using a second donor of primary RPTECs. In this study, 2 duplicate Mimetas 3-lane plates seeded with Lonza RPTECs (lot #18TL114340, top channel) and HUVECs (bottom channel) were exposed to cisplatin (10uM), tenofovir (100uM), PFOA (1uM), or were left untreated. Compounds were added either through the RPTEC or HUVEC channel to measure permeability in both directions, and determine if the RPTECs would preferentially uptake/secrete the compounds. Additionally, some chips were left “cell free” to act as blanks to compare against passive diffusion through the gel. Cells were cultured over 6 days before initiation of treatment. Media was sampled after 1, 2, 3, 5, and 7 days of treatment (total of 13 days culture), and compounds were refreshed with each media change. In addition to analytical chemistry (to monitor permeability of the compounds through the gel), media was collected and tested for LDH and KIM-1. Note that cisplatin analytical samples were not tested due to high operational cost of ICP-MS/MS, and the lack of usable data in the PFOA and Tenofovir samples. \r\n Lastly, viability testing (image based) was performed at endpoint to determine effects of compound treatments on the RPTECs and HUVECs. One plate was treated with lysis buffer for later analysis into transcriptomics, and one plate was fixed for imaging, though due to high background fluorescence in the gel lane, results were inconclusive.\r\n\r\n\r\nConclusions:\r\n•\tThis lot of RPTECs (#18TL114340) did not invade into the gel like the previous lot tested, even by endpoint at day 13. \r\n•\t Analytical data confirmed that the gel provided a significant barrier to permeability of the tested compounds. Even after being exposed to treatments for 1 week (day 7 exposure), ~7% PFOA, and ~20% tenofovir was able to pass through the gel of blank, cell-free chips (Cisplatin analysis is still in progress). The addition of RPTECs and HUVECs to the cell channels decreased permeability by 2-10% on average, but it was not possible to determine uptake vs secretion in this system, as equilibrium was never reached through the gel layer in the middle. \r\n•\tLDH testing in effluent showed that when added to the RPTEC channel, cisplatin caused large increases in LDH release in RPTECs, but did not affect HUVECs on the opposite side of the gel. Other treatments (Tenofovir, PFOA) did not affect LDH release in either channel at the tested concentrations. Other treatments did not cause changes in LDH release compared to controls. \r\n•\tKIM-1 was increased slightly in all treatment conditions (Cisplatin, Tenofovir, PFOA; added through either RPTEC or HUVEC channel) compared to controls, except for when cisplatin was added directly to the RPTEC channel. In this treatment condition, KIM-1 release decreased significantly after 1 day of exposure, and continued to drop throughout additional exposure days, indicating a decrease in viability of the RPTECs, which were no longer present to secrete this marker (these results match the previous study with donor #18TL117405). \r\n•\tViability testing (image based; Nuclear stain + PI) indicated that when Cisplatin was added to the RPTEC channel, viability decreased in both channels (65% viability in RPTEC channel; 14% in HUVEC channel compared to untreated controls). When added to the HUVEC channel, a significant decrease in viability was only observed in the HUVEC channel (17% viability), indicating that HUVECs were sensitive to cisplatin treatment, regardless of where in the chip it was added. These results are nearly identical to the previous study (kidney study 17) with the alternative donor. However, in this study, tenofovir did not affect viability of the RPTECs (when added to either channel), but had a greater effect on the HUVECs (69% viability when added through RPTEC channel; 46% when added directly through HUVEC channel), though standard deviation was high on these measurements. Lastly, PFOA did not significantly affect viability in RPTECs or HUVECs under any condition. \r\n•\tThe gel layer continues to be an issue for permeability, making transport studies challenging in this platform."

"description": "In this study, basic hepatic function and metabolic capacity were evaluated to select the optimal hepatocyte batch to use for future MPS platforms. On Day 0, primary human hepatocytes (PHH, Lonza, HUM183231) with collagen were injected into the extracellular matrix (ECM) lanes of the Mimetas 2-lane plate. After that, hepatocyte maintenance media was added to the perfusion lanes. Media was collected and refreshed at least once every two days. The plate was incubated at 37°C with perfusion by rocking. Cultures were treated with midazolam (MDZ, 5uM) for 24hrs on Days 4, 8, and 12. After 24hrs of MDZ exposure, the remaining MDZ and produced metabolites were measured by LC-MS/MS. Cell viability analysis using Propidium Iodide was conducted on Day 14. To evaluate basal hepatic function and the hepatotoxicity due to MDZ, albumin, BUN, and LDH in the effluent were measured on Days 4, 8,12, and 14. In addition, the CYP3A4 /Luciferin-IPA assay using cultured cells was conducted on Days 4, 8, 12, and 14. PHHs were also seeded on a CNBIO LC12 plate and 96-well plate (sandwich culture), and metabolic capacity and basal hepatic function were evaluated under similar conditions. Those results were compared with the Mimetas 2-lane model (see TEX-VAL-PK-2021-08-19-Liver_CNBIO LC12_Exp.3_PHH (LZ HUM183231) with Midazolam)."

"description": "This study consisted of 2 arms – the first arm involved the TERT1/RPTEC-basal line, and the second was with the TERT1/RPTEC-OAT1 line. In each arm of the study, 6 plates were seeded (3 fluidic – CNBio T12; 3 static – Transwell). One plate was for Cisplatin (10uM) exposure, one for Tenofovir (100uM) exposure, and the last plate was for PFOA (1uM) exposure. Cells were cultured in static or fluidic conditions for 10 days, then compound treatment was initiated. Compounds were either added to the top chamber (B->A transport), or the bottom chamber (A->B transport) on days 10, 11, 12, 14, and 16 to determine differences in transport from apical or basolateral sides of the RPTECs. Media was collected on these exposure days to monitor LDH, KIM-1, and transport of compounds across the membrane via analytical chemistry (LCMS for Tenofovir and PFOA; ICP-MS for Cisplatin). TEER was measured throughout culture, and at endpoint, wells were selected for lysis (transciptomics), or permeability (10, 70kDa Dextran) followed by fixation for Immunocytochemistry (ZO-1, OAT1).\r\n\r\nConclusions:\r\n•\tSample analysis currently in progress, however some preliminary data has been analyzed – see below.\r\n•\tTEER peaked for TERT1-basal cells around day 8 (120 Ω*cm2 static, 80 Ω*cm2 fluidic), and day 6 in TERT1-OAT1 cells (160 Ω*cm2 static, 140 Ω*cm2 fluidic). TEER remained constant in the basal line, however began to steadily drop in the OAT1 line over time. As for treatments, in the basal line, TEER was increased significantly when Cisplatin (10uM) was added to the top chamber (basolateral surface of the cells) in fluidic cultures only. No other compound-induced changes in TEER were observed under any culture configuration or compound treatment. These treatments were intended as “non-toxic” so changes in TEER were not expected. \r\n•\tPermeability to 3kDa dextran was higher in all static conditions compared to fluidic (tighter barrier function in fluidic cultures). Compound treatments slightly lowered permeability compared to untreated controls – it is possible the cells were tightening up barriers in response to the treatment with these compounds to reduce passive diffusion. No significant difference was observed from A->B or B->A direction in 3kDa dextran permeability, indicating that this is a passive diffusion based process. Similar patterns were observed in experiments with the 70kDa dextran, however, overall permeability was 2-5 fold lower, indicating that the diffusion rate is size-dependent.\r\n•\tOAT-1 expression (through ICC staining) was higher in fluidic cultures compared to static counterparts in untreated controls. Treatments with the selected compounds/concentrations did not show any clear patterns in changes of OAT-1 expression. \r\n•\tAnalytical chemistry, LDH release, KIM-1 secretion, and additional imaging are still in progress, and will provide additional insight."

"description": "In this study, Lonza primary RPTECs were seeded in both the CNBio System (TC12) and Transwell cultures (TW). RPTECs were seeded on either the apical or basolateral surface of the membranes to determine the effects of direct flow on the monocultures. 24 wells/chips were seeded into each growth platform (TC12, TW). 12 wells/chips from each platform were cultured in each seeding configuration (apical or basolateral), and within each of those groups, 6 had media changes every 24h, and the other 6 had media changes every 48h. TC12 cultures were grown under a flow rate of 1uL/s, and TW were static. Cultures were taken out over 17 days, with media changes and TEER measurements throughout. At endpoint, cultures were tested for pAH (para-aminohippuric acid) secretion, permeability testing, and viability testing.\r\n\r\nConclusions:\r\n•\tTEER remained low throughout culture period (8-15 Ohm*cm2) with the primary RPTECs compared to previous studies with TERT1-RPRECs, where TEER remained near 100 Ohm*cm2). Maximum TEER was achieved around day 8, and began to drop for the remainder of the culture period until endpoint at day 12. TEER was slightly higher in static cultures, and in bottom seeded vs top seeded cultures, which is concordant with previous studies. \r\n•\tPermeability to FITC-dextran (150kDa) was significantly higher in top seeded cultures compared to bottom seeded, indicating greater barrier function when cells are seeded on the bottom of the membrane. Additionally, static cultures were generally more leaky (higher permeability) than their fluidic counterparts. \r\n•\tWater transport was not observed with these primary cells as previously shown in the TERT lines. In all conditions, volume is increasing in the bottom chamber. Additionally, this observation appears to be cumulative, as the “48hr media change” cultures had greater accumulation of volume in the bottom well than the “24hr media change” groups. \r\n•\tPrestoBlue was used as a non-destructive method for viability testing, and indicated no difference in viability in top vs bottom seeded cultures (which is in agreement with previous studies). Additionally, viability was slightly higher (though not significant) in fluidic cultures compared to static counterparts. \r\n•\tpAH secretion studies showed no difference in cell seeded cultures vs blanks, therefore these cells were not actively secreting pAH, and any transport observed was due to passive diffusion between chambers. Mannitol showed similar trends. \r\n•\tImmunocytochemistry revealed significant differences in monolayer formation between top and bottom seeded cultures. Nuclear staining revealed that when cells were seeded on the top of the membrane, they formed large clusters, with many “holes” in the monolayer. Cells only formed flat monolayers when seeded on the bottom of the membranes. “48h media change” cultures showed more evenly spread monolayers, and better overall density of cells compared to the “24h media change” conditions. Therefore the additional media changes may induce additional stress in cultures. Lastly fluidic cultures showed significantly higher density of cells compared to static conditions. Overall, the best configuration for culturing cells appeared to be bottom seeded, 48h media change conditions in fluidic cultures. \r\n•\tAQP1 expression (confirmed via ICC) was 2-3 fold higher in fluidic conditions compared to static, and media change frequency did not appear to have an effect on AQP1. Top seeded conditions showed higher AQP1 staining, though this did not appear to be significant.\r\n•\tSGLT2 expression (confirmed via ICC) was higher in static conditions compared to fluidic. Media change frequency did not appear to have an effect on SGLT2, however expression was higher in top seeded cultures vs their bottom seeded counterparts."

Media was collected and refreshed at least once every two days (Except on Days 1 to 4 - the same medium was used for 3 days). The plate was incubated at 37°C with the Incubate program (flow rate: 1 µL/s). Cultures were treated with 5 µM midazolam (MDZ) for 24hrs on Days 4, 8, and 12. After 24hrs of MDZ exposure, the remaining MDZ and produced metabolites were measured by LC-MS/MS. Total protein assay was conducted on Day 14 to measure the total protein content of cells in culture. To evaluate basal hepatic function, albumin, BUN, and LDH in the effluent were measured on Days 4, 8,12, and 14. In addition, the CYP3A4/Luciferin-IPA assay using cultured cells was conducted on Days 4, 8, 12, and 14. PHHs were also seeded on a 96-well plate (sandwich culture), and metabolic capacity and basal hepatic function were evaluated under similar conditions. These results were compared with the CNBIO LC12 plate model."

In configuration 1, all cell types were seeded into the top channel, and the bottom channel was left blank. In configuration 2, podocytes and mesangial cells were seeded into the top channel, and glomerular endothelial cells into the bottom channel. 4mg/mL collagen I gel was used as the barrier in the central channel of all chips. Cells were cultured under rocking conditions (7°, 8 min intervals) for 3 days before endpoint. Phase contrast images were collected daily throughout culture, and on the final day of culture, permeability was assessed by adding FITC-Dextran (150kDa) or FITC-hBSA to the top channel and monitoring fluorescence in the effluent of the bottom channel after 1 hr. Additionally, viability testing was performed (image based: Nuclear staining, PI) to determine effects of seeding configuration on cell viability.\r\nConclusions:\r\n•\tCells seemed to grow with high viability in both seeding configurations, however a good barrier to dextran and BSA was not established. \r\n•\tFurther optimization is necessary for these cells to establish barrier function and glomerular basal membrane (GBM) secretion. \r\n•\tViability was similar between seeding configurations.\r\n•\tPermeability was lower (better barrier function) in configuration 2, where the cells were seeded in the 2 separate channels. However, permeability was still near blank (cell-free) levels, so cells were not providing a good barrier under either condition.\r\n•\tTiming is crucial in the seeding of these cells – too short of a growth period does not allow for barrier formation, however cells quickly begin to invade into the matrix, making longer-term experiment a challenge."

G-node integration in rectangular tissue with sharp and rounded corners. G-nodes integrated into a rectangular tissue predominantly activated the muscle construct compared to the four corners of the muscle tissue. Furthermore, the rounded corner decreased the empirical probability of initial activation at the corner, and thus the activation probability of the integrated G-node in the rounded tissue increased to 91%. Different shapes of G-node in rounded rectangular tissue. The square and diamond G-nodes have a similar probability of activation at the G-node to the circular design (83 and 87% vs. 91%). This indicates that an acute angles in the small source tissue like the G-node is not critical in determining the activation site. Rather, it is the fewer number of cells in the smaller G-node tissue that acts as a source to initiate muscle activation."

"description": "In this study, 6 RPTEC sources were seeded in both the CNBio System (TC12) and Transwell cultures (TW). RPTECs were seeded on either the apical or basolateral surface of the membranes to determine the effects of direct flow on the monocultures. 12 wells/chips were seeded into each growth platform (TC12, TW). 6 wells/chips from each platform were cultured in each seeding configuration (apical or basolateral) - see design image below.\r\nTC12 cultures were grown under a flow rate of 2uL/s, and TW were static. Cultures were taken out between 9-18 days (depending on cell source), with media changes and TEER measurements throughout. At endpoint, cultures were tested for pAH (para-aminohippuric acid) secretion, mannitol secretion, permeability testing, and protein expression (Immunocytochemistry, image-based quantification). pAH and mannitol secretion was tested at 1, 2, and 24h after addition to media chambers.\r\n\r\nConclusions:\r\n•\tSignificant differences in TEER were observed between cell sources. Primary RPTECs (Biopredic and Lonza) remained stable, but low throughout culture period (both ~10 Ω*cm2, up to 14 days in culture). TERT lines were variable – The basal line reached its peak TEER around day 8 (150 Ω*cm2 static, 100 Ω*cm2 fluidic), TERT-OAT1 peaked around day 2-4 (120 Ω*cm2 static and fluidic), TERT-OCT2 peaked around day 8 (30 Ω*cm2 static, 18 Ω*cm2 fluidic), and TERT-OAT3 peaked around day 8 (100 Ω*cm2 static, 80 Ω*cm2 fluidic). Overall, static growth conditions led to higher TEER than fluidic counterparts. Additionally, when cells were seeded on the bottom of the Transwells, TEER was further elevated (by 10-20 Ω*cm2 in TERT parent, OAT1, and OAT3 lines). \r\n•\tPermeability to 70kDa FITC-Dextran was higher in static vs fluidic conditions, and also in top vs bottom seeded conditions. The growth conditions with the tightest barrier to diffusion (lowest dextran permeability) were bottom seeded, fluidic cultures. Within this configuration, all TERT lines showed 1-2% permeability (relative to blanks), and primary cells had 3-4% permeability. To compare, primary cultures in static conditions when grown on the top of the membrane had up to 25% permeability.\r\n•\tWater transport (as observed by differences in ABS) was only observed in the basal TERT1 line, and to a lower degree, in OAT1 lines. Water transport was not observed in the remaining TERT1 lines, or in primary cells. \r\n•\tImmunocytochemistry revealed significant differences in monolayer formation between cell sources. All TERT1 lines showed nice, dense, even monolayers across the membranes in all conditions (top vs bottom; static vs fluidic). However, as previously demonstrated in earlier studies, the primary cells formed large clusters of cell aggregates rather than an even monolayer. \r\n•\tAQP1 expression (confirmed via ICC) was ~30% higher in primary cell cultures compared to TERT1 lines. No significant difference in AQP1 was observed between top/bottom seeding conditions, however AQP1 was markedly higher in fluidic cultures. \r\n•\tSGLT2 expression (confirmed via ICC) was higher in OAT1 cultures, than other cell sources. Additionally, SGLT2 was slightly elevated (though non-significant) in top seeded configurations. No difference was observed in static vs fluidic cultures. \r\n•\tFor future studies, RPTECs will be seeded on the bottom of membranes – this appears to result in more even monolayer formation, and higher barrier function over time. Now that a seeding configuration has been determined, future studies can involve compound treatments with more replicates."

"description": "In this study, 2 duplicate Mimetas 3-lane plates seeded with Lonza RPTECs (lot #18TL117405, top channel) and HUVECs (bottom channel) were exposed to cisplatin (10uM), tenofovir (100uM), PFOA (1uM), or were left untreated. Compounds were added either through the RPTEC or HUVEC channel to measure permeability in both directions, and determine if the RPTECs would preferentially uptake/secrete the compounds. Additionally, some chips were left “cell free” to act as blanks to compare against passive diffusion through the gel. Cells were cultured over 6 days before initiation of treatment. Media was sampled after 1, 2, 3, 5, and 7 days of treatment (total of 13 days culture), and compounds were refreshed with each media change. In addition to analytical chemistry (to monitor permeability of the compounds through the gel), media was collected and tested for LDH and KIM-1. Lastly, viability testing (image based) was performed at endpoint to determine effects of compound treatments on the RPTECs and HUVECs. One plate was treated with lysis buffer for later analysis into transcriptomics, and one plate was fixed for imaging, though due to high background fluorescence in the gel lane, and significant cell invasion, results were inconclusive.\r\n\r\nConclusions:\r\n•\tThis lot of RPTECs (#18TL117405) showed significant invasion into the gel by day 6 when compound treatment was initiated. This experiment will be repeated with another lot of Lonza primary cells, as invasion into the gel will certainly affect permeability. \r\n•\tAnalytical data confirmed that the gel provided a significant barrier to permeability of the tested compounds. Even after being exposed to treatments for 1 week (day 7 exposure), ~30% cisplatin, ~12% PFOA, and ~8% tenofovir was able to pass through the gel of blank, cell-free chips. The addition of RPTECs and HUVECs to the cell channels decreased permeability by 2-10% on average, but it was not possible to determine uptake vs secretion in this system, as equilibrium was never reached through the gel layer in the middle. \r\n•\tLDH testing in effluent showed that when added to the RPTEC channel, cisplatin caused large increases in LDH release in RPTECs, and a slight increase in HUVECs on the opposite side of the gel. Other treatments (Tenofovir, PFOA) did not affect LDH release in either channel at the tested concentrations. When added to the HUVEC channel, cisplatin caused a similar decrease in LDH release (likely due to acute cell death) in both RPTEC and HUVEC channels. Other treatments did not cause changes in LDH release compared to controls. \r\n•\tKIM-1 was increased slightly in all treatment conditions (Cisplatin, Tenofovir, PFOA; added through either RPTEC or HUVEC channel) compared to controls, except for when cisplatin was added directly to the RPTEC channel. In this treatment condition, KIM-1 release decreased significantly after 1 day of exposure, and continued to drop throughout additional exposure days, indicating a decrease in viability of the RPTECs, which were no longer present to secrete this marker. \r\n•\tViability testing (image based; Nuclear stain + PI) indicated that when Cisplatin was added to the RPTEC channel, viability decreased in both channels (65% viability in RPTEC channel; 16% in HUVEC channel compared to untreated controls). When added to the HUVEC channel, a significant decrease in viability was only observed in the HUVEC channel (20% viability), indicating that HUVECs were sensitive to cisplatin treatment, regardless of where in the chip it was added. Tenofovir decreased viability in RPTECs by ~10% (when added to either channel), and decreased viability in HUVECs by ~15% (when added to either channel). Lastly, PFOA did not significantly affect viability in any condition. \r\n•\tThe gel layer continues to be an issue for permeability, making transport studies challenging in this platform."

The plate was incubated at 37°C with the Incubate program (flow rate: 1 µL/s). Cultures were treated with 5 µM midazolam (MDZ) for 24hrs on Days 4, 8, and 12. After 24hrs of MDZ exposure, the remaining MDZ and produced metabolites were measured by LC-MS/MS. Total protein assay was conducted on Day 14 to measure the total protein content of cells in culture. To evaluate basal hepatic function, albumin, BUN, and LDH in the effluent were measured on Days 4, 8,12, and 14. In addition, the CYP3A4/Luciferin-IPA assay using cultured cells was conducted on Days 4, 8, 12, and 14. PHHs were also seeded on a 96-well plate (sandwich culture), and metabolic capacity and basal hepatic function were evaluated under similar conditions. These results were compared with the CNBIO LC12 plate model."

"description": "In this study, we attempted a new gel formulation based on previously published work in another tissue chip model (PMID: 30833403). One of the main issues we have been facing with the Mimetas 3-lane plate is the lack of permeability of compounds/drugs to the opposite channel. Instead of using the 4mg/mL collagen type 1 recommended by Mimetas, we attempted a gel made from 1% gelatin, 25mg/mL fibrinogen, 2.5mM CaCl2 and 0.2% transglutaminase in hopes that this would increase permeability. We were able to successfully polymerize the new gel, however the new formulation did not improve permeability compared to the original formulation. Additionally, the longer incubation time of the new formulation caused some of the original gel lanes to dry up prior to testing permeability. Here, we show the results with phase contrast imaging, the addition of trypan blue to track leakage across the gel, and permeability of FITC-dextrans (10, 70, 150kDa) and FITC-BSA."

HUVECs were seeded on the basolateral side of the membranes, and TERT1/RPTEC-OAT1 cells were seeded on the apical surface of the membranes. 12 wells/chips were seeded into each growth platform (TC12, TW). 6 wells/chips from each platform were cultured in ATCC TERT1/RPTEC growth media only, and the other 6 were grown in ATCC TERT1/RPTEC growth media supplemented with Lonza EGM-2 supplements to help support the growth of the HUVECs. TC12 cultures were grown under a flow rate of 1uL/s, and TW were static. Cultures were taken out over 6 days with TEER measured throughout, and media collected from the top and bottom for LDH. At endpoint, viability was measured using PrestoBlue, and permeability was measured through the addition of FITC-dextran-150kDa to the basolateral chamber for 1h (and measuring permeability to the apical chamber). Lastly, membranes were fixed and imaged for ZO-1, VE-cadherin, OAT1, and DNA.\r\n\r\nConclusions:\r\n•\tTEER was higher overall (by ~10 Ohm*cm2) in static Transwell cultures, compared to their fluidic CNBio counterparts.\r\n•\tTEER began to decrease around day 3 of culture, but was maintained longer in cultures supplemented with the additional HUVEC media supplements compared to the REGM only. \r\n•\tPermeability to FITC-dextran (150kDa) was similar in all conditions, future studies will use a smaller size dextran to parse out differences in permeability. \r\n•\tImmunocytochemistry revealed that by day 6 of culture, there was a loss in epithelial barrier, and the RPTECs began to lift off the membrane. Therefore we should perform endpoint studies prior to observing this dip in TEER over time. \r\n•\tLDH release was low in 3D cultures of cells in the REGM media only, but increased 2-3 fold when cells were grown in static conditions, or when the HUVEC supplements were added to the “coculture” media. \r\n•\tCo-culture of HUVECs and RPTECs was challenging due to different media requirements, and even with HUVEC supplements added into the RPTEC media, viability remained low. Therefore future studies will focus only on monoculture of RPTECs.\r\n•\tHUVECs were grown on the bottom of the Transwell (in the path of fluid flow in the CNBio plate), however we are most interested in the effects of shear on the RPTECs, therefore in future experiments we will try top vs bottom seeding of RPTECs."

"description": "In this study, TERT1/RPTEC-basal (ATCC) cells were seeded in both the CNBio System (TC12) and Transwell cultures (TW). RPTECs were seeded on either the apical or basolateral surface of the membranes to determine the effects of direct flow on the monocultures. 12 wells/chips were seeded into each growth platform (TC12, TW). 6 wells/chips from each platform were cultured in each seeding configuration (apical or basolateral). TC12 cultures were grown under a flow rate of 1uL/s, and TW were static. Cultures were taken out over 11 days, with media changes and TEER measurements every 48h. At endpoint, cultures were tested for pAH (para-aminohippuric acid) secretion, permeability testing, and viability testing.\r\n\r\nConclusions:\r\n•\tWater transport was observed in all culture conditions (static, fluidic; top, bottom seeded) via measured changes in volume (determined by effluent mass) from the top and bottom chambers of wells. The highest degree of water transport was observed when RPTECs were basolaterally seeded, and in fluidic conditions. \r\n•\tMedia Absorbance (ABS) was also used to monitor water transport, and was determined to be a less invasive/destructive method for measurement than total effluent mass, as we could just measure a sample of media for ABS rather than the entire liquid volume in the chamber, which caused additional stress on the cells. \r\n•\tLDH was slightly elevated in fluidic cultures compared to static counterparts. There was no observable difference in top vs bottom seeded cultures. \r\n•\tpAH secretion was higher in cells that were seeded on the bottom of the Transwells (vs top seeded), and was also slightly higher in static vs fluidic cultures. \r\n•\tPermeability to FITC-dextran (150kDa) was similar in all conditions (static vs fluidic, top vs bottom seeded). A smaller size dextran will need to be used in the future to observe differences in permeability. \r\n•\tTEER peaked around day 6 in both static and fluidic conditions, and remained stable throughout the remainder of the culture period (up to day 10). TEER was higher (by ~25 Ohm*cm2) in static cultures compared to fluidic, and was further increased (by 5-10 Ohm*cm2) by seeding cells on the bottom of the membrane (compared to top seeded cells). \r\n•\tViability (CellTiterGlo) was similar across all seeding conditions."

On Day 0, primary human hepatocytes (PHH, Lonza, HUM183231) were injected into each well of a CNBIO PhysioMimix MPS-LC12 plate with hepatocyte plating media. Media was collected and refreshed at least once every two days (Except on Days 1 to 4 - the same medium was used for 3 days). The plate was incubated at 37°C with the Incubate program (flow rate: 1 µL/s). Cultures were treated with 5 µM midazolam (MDZ) for 24hrs on Days 4, 8, and 12. After 24hrs of MDZ exposure, the remaining MDZ and produced metabolites were measured by LC-MS/MS. Total protein assay was conducted on Day 14 to measure the total protein content of cells in culture. To evaluate basal hepatic function, albumin, BUN, and LDH in the effluent were measured on Days 4, 8,12, and 14. In addition, the CYP3A4/Luciferin-IPA assay using cultured cells was conducted on Days 4, 8, 12, and 14. PHHs were also seeded on a 96-well plate (sandwich culture), and metabolic capacity and basal hepatic function were evaluated under similar conditions. These results were compared with the CNBIO LC12 plate model. (see TEX-VAL-PK-2021-08-19-Liver_Mimetas 2-lane_Exp.5_PHH (LZ HUM183231) with Midazolam)."

"description": "In this study, we attempted a few new gel formulations based on fibrinogen or agarose as suggested by the Consortium group. One of the main issues we have been facing with the Mimetas 3-lane plate is the lack of permeability of compounds/drugs to the opposite channel. Instead of using the 4mg/mL collagen type 1 recommended by Mimetas, we attempted to load chips with gels made from 0.2% or 0.5% agarose, or 5 or 25mg/mL fibrinogen in hopes that this would increase permeability. We were able to successfully polymerize the new gels, however the new formulations did not improve permeability compared to the original formulation, and success rate was low. Only 5 chips (1 from each gel loading condition are shown here -- see images). \r\n\r\nNote: This study has images only, no quantitative data was collected due to low success rate.\r\n\r\nConclusions:\r\n-The 0.2 and 0.5% agarose gels had negligible differences in gel permeability from the original formulation, however they were significantly more difficult to load into chips, as they had to be kept near-boiling, and would typically stiffen in the pipette before even being loaded into the gel lanes. \r\n-The 5mg/mL fibrinogen gel was not stiff enough to hold up in the ECM lane, and collapsed when buffer was added. \r\n-The 25mg/mL fibrinogen gel was stiff enough to create an ECM barrier, but permeability was lower than the original collagen gel formulation."

"description": "In this study, a Mimetas 3-lane plate was seeded in one of 2 configurations. RPTEC only – TERT1-Parent RPTECs in the top channel, and bottom channel left empty; or RPTEC + HUVEC – TERT1-parent RPTECs in the top channel, and HUVECs in the bottom channel. After cells reached confluency in both channels (3 days of rocking culture at 7 degrees, 8 minute intervals), chips were treated with CalceinAM, CMFDA, or 6-NBDG in the presence or absence of inhibitors (CyclosporineA, MK571, or Phlorizin, respectively) to measure influx/efflux transporter activity. After incubation with fluorophores +/- inhibitors, RPTEC channels were imaged to determine intracellular fluorescence levels. A 384 well plate was seeded with RPTECs only and used as a 2D comparator."
