Project 5: Systems Engineering & Analysis for Organotypic Culture Models
Summary/Accomplishments (Outputs/Outcomes):
Project 1: Mammosphere Bioreactor For Life-Stage Specific Toxicology
Project 2: Organotypic Culture Model to Analyze Developmental Limb Malformations Resulting from Toxicant/Teratogen Exposure
Using these cultures, timelines of chondrogenic and hypertrophic (1) gene expression, (2) matrix elaboration and (3) histochemical and immunohistochemical marker detection in both the chondrogenic and hypertrophic cultures were analyzed. In collaboration with Project 5, a new mechanical stimulator for a joint segmentation model amenable to microscopy and microfluidics that maintains the region-of-interest in a focal plane was developed. These 10ul cultures were used to test the effects of 3 known teratogens (valproic acid, warfarin and thalidomide) on adult human MSC micromass culture chondrogenesis and hypertrophy. Using outcomes based on RT-PCR, immunohistochemistry and biochemistry, effective doses approximating reported maternal plasma levels were observed. Initial tests for the effect of two candidate teratogens (bisphenol A and mifepristone) on adult human MSC chondrogenesis and hypertrophy were also been performed. To reduce cell numbers for each assay, Project 2 successfully developed planar micromass cultures comprising of only 40,000 cells on texturized, Col I coated polystyrene multiwell plates. These cultures were further optimized by the addition of a gel overlay comprised of 5% w:v photocrosslinkable gelatin, PXL mGL, which increased the morphologic consistency between cultures and experiments significantly. The increased utility of the gel overlay was evident in our work with the GFP collagen type 2 promoter. In gel-overlay cultures, the number and intensity of GFP positive cells could be reliably counted. We compared the fold change in Col2 gene expression assayed by RT-PCR with the corrected total cell fluorescence (CTCF) fold change and found excellent agreement. Previous work showed the current model was insensitive to thalidomide treatment, a known and potent limb teratogen, at doses as high as 1mM thalidomide. A putative mechanism of thalidomide action maybe by preventing angiogenesis during limb formation via disruption of normal cereblon-mediated protein turnover and concomitant changes in gene expression. In light of this, the gel overlay was used to incorporate GFP-labeled HUVECs into our limb OCMs. OCMs that included MSCs overlaid with HUVECs showed a very significant decrease in chondrogenic gene expression in the presence of thalidomide. We have determined our cultures express cereblon and ikaros by Western blot analysis. We hypothesize that thalidomide will decrease cereblon and ikaros in both MSC and HUVECs, angiogenesis will be completely inhibited, and MSC chondrogenesis will be decreased. Work also continued on developing the OCM3 joint segmentation model. PXL mGL was used to encapsulate MSCs in the troughs of our concentric ring model which eliminated prior problems with leakage and non-uniform chondrogenesis. Manual flexing of 1 hr a day for 7 days resulted in cultures with decreased matrix deposition and increased GDF5 expression at the site of flexion suggesting that interzone like changes are occurring in this OCM model. Our group utilized 3D printing to create prototypes of microfluidically enabled OCM 1 and 2 cultures which consisted of upper and lower chambers separated by polycarbonate membranes with low profiles for microscopy and small medium chambers useful in conservation of reagents and downstream ELISA assays. Project 2 also verified the process of hypertrophy in the reduced cell number cultures. RT-PCR revealed T3 stimulation induced strong hypertrophic gene expression (COLX and MMP13). Chondrogenic genes (COLII and AGG) were initially down-regulated with the addition of T3 (as expected), but increased again over the next 7 days. This “recovery” was not observed in the 10uL cultures. That hMSCs in the micromass cultures co-express chondrogenic and hypertrophic genes during differentiation, lead us to hypothesize that perhaps induced pluripotent stem cells (iPSCs) might undergo sequential chondrogenesis and hypertrophy (as in the embryo) and more faithfully report the effect of environmental toxins on chondrogenesis and hypertrophy. Trends in iPSC differentiation appeared similar to that of bone marrow-derived MSCs (BM-MSCs), but gene expression values were much lower and cultures showed poor morphology. Refinement of the dose responses of 2ul (40,000) chondrogenic and hypertrophic cultures to known and unknown teratogens was also studied. The initial dose responses to valproic acid (VPA), warfarin, thalidomide, mifepristone and bisphenol A (BPA) utilized drug concentrations over 5 orders of magnitude. Using VPA as a test, restricting the dose range to one or two orders of magnitude, we were able to separate effective concentration (defined by 50% reduction in the marker gene expression) and lethal concentration (defined by a 50% reduction in cell viability) for both chondrogenesis and hypertrophy. We also assessed the activity of a validated COL2 promoter reporter developed in VPA-exposed chondrogenic micromass cultures. This is essential for the future non-invasive analysis of both healthy and toxin-exposed micromass cultures. Project 2 worked closely with Project 5 to develop an automated joint segmentation reactor. MSCs-based constructs cultured in this bioreactor were viable after 2 weeks and showed robust Alcian blue staining, indicating that MSCs can reach chondrogenic differentiation in this bioreactor setup. We also refined a design to our 3D printed low-profile microfluidically enabled bioreactor for OCM 1 and 2 cultures to enable uniform flow over the cultures with multiple configurations in one and two chamber form. 2 mL drops containing 40,000 MSCs was spotted on the polycarbonate membrane of the microfluidics enabled bioreactor. Cells were left to adhere for up to 60 minutes and the chamber filled with fresh chondrogenic medium, sealed with a glass coverslip and connected to the P5 microfluidic system. MSCs were viable in the bioreactor for 48 h after seeding. Imperfections in the printing requires us to adapt the reactor to PDMS manufacture in order to sustain a culture for 14 or 17 days. Liver OCMs (Project 4) were challenged with 0 uM, 100uM, 1mM, 2mM VPA in chondrogenic media. This conditioned media was then mixed 1:1 with fresh chondrogenic media. Limb OCM micromass cultures grown in the liver conditioned media formed at all the VPA doses tested but all doses of VPA showed decreased Collagen II gene expression with the highest dose (2mM) showing the largest decrease.
Project 3 - Validating a fetal membrane on a chip model for characterizing reproductive toxicant exposure risks
- Specific Aim 1: Define the temporal and concentration-dependent effects of TCDD on native fetal membrane immune responses to infection. Native fetal membranes from non-laboring women at delivery exhibit an enhanced responsiveness to an infection mimic (lipopolysaccharides (LPS, 10 ng/ml)) following pretreatments with TCDD (10 nM). These findings supported our central hypothesis that environmental toxicants prime the gravid uterus for exaggerated inflammatory responses.
- Specific Aim 2: Implement an in vitro, microscaled, living, instrumented fetal membrane on-a-chip (IFMOC) that recapitulates the physiological properties of the human tissue. The overarching goal of the current application is to determine the utility of the IFMOC compared to traditional cultures for screening of individual toxicants.
- Specific Aim 3: Validate the IFMOC as a model of environmental toxicant immunomodulation compared with primary human fetal membranes. As noted above, using multiple organotypic (OoC) devices, we have exposed the primary cell types that comprise the endocrine/immune sensitive cells of the human maternal-fetal interface to a variety of toxicants and/or inflammatory agents.
Project 4: Organotypic Liver Model for Predictive Human Toxicology and Metabolism
Much of our final year efforts were focused on coupling our Liver OCM to the OCMs from other projects. Multiple factors such as media, scaling, flow rate, hardware compatibility and other issues were addressed prior to the integration. Our initial approach to integration was using functional coupling (media is conditioned in the liver OCM, then used to perfuse another OCM [3]). In order to prepare conditioned media for functional coupling, we used allometric scaling to calculate the appropriate amount of liver conditioned media to provide to the other project teams. After the appropriate scaling was determined, we selected relevant test compounds for OCM treatment. Drugs were chosen based upon availability of reference clinical data and distribution of liver activities (non-toxic, known toxic, metabolized). Compounds with cLogP ≤ 3 were selected to minimize issues of drug binding to PDMS [7]. Treated and control liver conditioned media were prepared for 8 compounds and delivered to Projects 1,2,3, and 5 (Table 2). As preparation for physical integration, we trained the Vanderbilt project teams to recapitulate our liver OCM. All protocols and SOPS for Liver OCM assembly and assays uploaded to the VPROMPT SharePoint site and the MPS database (https://mps.csb.pitt.edu/), were reviewed and approved. All components are commercially available and detailed in the SOPs. We continued to validation iPSC hepatocytes from a collaborator.

Conclusions:
Project 1: Mammosphere Bioreactor For Life-Stage Specific Toxicology
Project 2: Organotypic Culture Model to Analyze Developmental Limb Malformations Resulting from Toxicant/Teratogen Exposure
Project 2 demonstrated successful chondrogenesis and hypertrophy of adult human MSCs in planar high-density culture comprised of 400,000 cells each in 10ul volume.
Project 3 : Validating a fetal membrane on a chip model for characterizing reproductive toxicant exposure risks
Using identical treatments with estradiol (1nM) and medroxyprogesterone acetate (500 nM) during the decidualization phase within our devices we have confirmed the cellular responses within the devices relative to the responses observed in the transwell system. Our studies reveal the utility of these devices to examine important physiological processes that can be disrupted by exposure to various toxicants.
| Device | Description | Comment |
| IFMOC | Multi-chamber device to mimic human fetal membrane | This highly complex device will be useful for mechanistic studies but is not amenable for use as a screening tool. |
| MFI | Two chamber device containing endometrial stromal cells and placental trophoblasts | Appropriate for both toxicant screening and mechanistic studies of secondary exposures. Can additionally allow for the introduction of immune cells to study immune dysfunction. |
| LIver/MFI | Connect the liver OoC to the MFI | Although feasible in theory, timing constraints associated with acquisition of multiple human tissues limits the utility of this approach. |
| LIver CM/MFI | Expose the MFI to liver conditioned media (CM). | Liver CM, from the Liver OoC treated with toxicants, can readily be added to the MFI device to more effectively test the impact of liver metabolism of toxicants on the early pregnancy environment and common infections. |
| EndoChip | Two chamber device of the human endometrium | Appropriate response to steroids resulting in endometrial stromal cell decidualization is critical to establishment of pregnancy; thus, examining the impact of toxicants in a “non-pregnant” system is relevant. |

Project 4: Organotypic Liver Model for Predictive Human Toxicology and Metabolism
Matured iPSC-derived human hepatocytes were obtained from a collaborator in order to take advantage of his patented iPSC hepatocyte maturation methodology. The functionality of the iPSC hepatocytes was determined by testing a metabolism probe mixture for three specific isoforms of human Cytochrome P450 and two for glucuronidation. In that study, comparing iPSC derived human hepatocytes and a pool of 20 human donors of cryopreserved hepatocytes functional biomarkers such as albumin and urea secretion were comparable, and the oxidative metabolism activity found in iPSC cells for Cyp -1A2, -3A4 and -2C9 were 85 – 123% of donor pool levels. Finally, the results from a compound study are recently published in the 2020 Lab on a Chip.
