Visit Poster #2057: Multi-parametric 3D tumor microtissue-based phenotypic compound classification by Dr. Jens Kelm of InSphero (co-authored by NCATS/NIH). Poster Abstract: Phenotypic assays are a powerful tool in drug discovery. However, the predictive value of phenotypic drug testing depends on how close we can mimic the in vivo environment and the biomarker used to assess the clinical response. The closer we mimic the tissue environment and the respective disease progression the better the predictive value of an assay to discover and develop new therapeutics. 3D model systems can better reflect the cell composition, inter-cellular interaction, tissue structure, and biological characteristics of primary tumors. Here, we report on the development of homo- and heterotypic ovarian and pancreatic microtissue tumor models amenable for a screening assay of up to 40 compounds selected from the NCATS Oncology library. The compounds were chosen to target different mechanisms driving tumor cell growth and survival. The goal of this study was to develop a high throughput compatible drug screening assay based on 3D multicellular spheroids from ovarian (HEY-A8 and SKOV) and pancreatic (Panc-1) cancer which enables the discrimination of tumor-specific efficacy and unspecific cytotoxicity of a drug candidate with subsequent identification of the molecular mechanism of action (MMOA). The biological response measured over a 10-day drug exposure period included (i) growth kinetics (microtissue size), (ii) potency (IC50ATP_10_days) and efficacy (max. response ATP and size). The biological response of the compounds was compared between the different cell culture formats tested, 2D, 3D homotypic and 3D heterotypic. The comparison of IC50 values among the different ovarian cancer cell cultures showed that 21 out of the 38 compounds tested were more potent in 3D than in 2D. Within the pancreatic models, 13 out of 20 compounds tested were more potent in 3D than in 2D. Interestingly, most of the compounds which showed stronger potency in 3D were targeted small molecule agents. Comparing drug responses of homo vs heterotypic ovarian tumor model systems, 3 compounds were effective only in the heterotypic model including the WNT inhibitor PNU-74654 and GABA uptake inhibitor (Gat-1) SK&F-89976A. We also evaluated non-specific cytotoxic effects on the incorporated NIH3T3 fibroblasts by quantifying a secreted reporter over time. The assay system allowed us to discriminate between acute cytotoxic effects (3-day exposure) and sub-chronic toxicity (7-day exposure). Whereas only a very limited number of compounds had acute cytotoxic effects, there were considerable more compounds with sub-chronic cytotoxicity. Based on the single endpoint classifications, we choose an mTOR inhibitor, Torin-2, to further assess molecular mechanism of cell death action for all three tumor microtissue models used in this study using reversed phase protein assay and transcriptome analysis. In summary, we present a 3D tumor microtissue-based phenotypic drug discovery testing scheme which allows a multi-parametric endpoint analysis paired with subsequent molecular pathway identification.

 

Monday, January 25, 1:00 - 3:00 PM
Visit Poster #2189: Simplifying 3D microtissue-based screening using automation and image based cytometry on the EnSight multimode plate reader to generate and characterize scaffold-free 3D cell cultures, by Ann (Shang-pin) Kwei of PerkinElmer.  Poster Abstract:  3D cell culture spans the gap between the traditional “petri-dish-based” format and whole-animal systems by both mimicking features of the in vivo environment and taking advantage of the same tools used to study cells in traditional cell culture, thus giving unique perspectives on tumorigenesis. Process standardization is essential to enable the generation of robust and reproducible data with more biologically relevant, but complex, 3D models. Here we demonstrate how producing and characterizing 3D spheroid microtissues with the InSphero GravityPLUS™ hanging drop microplate platform can be simplified and standardized by integrating automated liquid handlers with the EnSight™Multimode plate reader to reduce variability, hands-on time, and errors produced by manual pipetting. Process steps include: (i) using automation to generate hanging drop cultures in the InSphero GravityPLUS™ plate, (ii) automated transfer of the hanging drop cultures to the GravityTRAP™ ultra-low attachment plates for long-term growth, and (iii) automated media exchange and compound treatment in these plates. Tumor microtissue growth was assessed directly in the GravityTRAP™ plate using the imaging module of the EnSight™ plate reader and a custom-developed analysis procedure for basic 2D characterization that automatically identifies and measures spheroid area from brightfield images. This allows for rapid monitoring of tumor microtissue growth over time without necessitating addition of a fluorescent label. Tissue viability and proliferation was assessed further using the ATPlite™Luminescence Assay system in which spheroids are thoroughly lysed and ATP content assessed. Overall, a fully automated microtissue production and assay set-up is being presented to monitor growth and viability to further foster the use of more biologically relevant 3D models on an industrial scale.
