Objective:
The proposed project will generate a high throughput neurotoxicity screening platform that recapitulates the phenotypic diversity within the human central nervous system (hCNS) while still being sensitive enough to detect toxicity towards a single phenotype.
Approach:
Novel differentiation protocols and innovative microfabrication techniques will be used to generate a microfluidic screening platform comprised of an array of 3D organotypic tissues derived from human pluripotent stem cells and differentiated into region-specific tissues that span the hCNS.
Expected Results:
Collectively, we hypothesize that the tissues will capture an unparalleled amount of hCNS phenotypic diversity, and their development will be modeled using RNA-seq analysis to comprehensively capture this diversity and provide fundamental insights into signaling pathways that govern their development, function, and can potentially be targeted by toxins. Furthermore, we will use Cas9-mediated genome editing to increase the versatility of our organotypic hCNS model. In combination with high-content imaging, our microfluidic screening platform will be ideal for executing quantitative high throughput screening assays to generate predictive dose-response data on toxins with neural phenotype-specific effects.
