High-Dimensional Design-Of-Experiments Extracts Small-Molecule-Only Induction Conditions for Dorsal Pancreatic Endoderm from Pluripotency.


ABSTRACT: The derivation of endoderm and descendant organs, such as pancreas, liver, and intestine, impacts disease modeling and regenerative medicine. Use of TGF-? signaling agonism is a common method for induction of definitive endoderm from pluripotency. By using a data-driven, High-Dimensional Design of Experiments (HD-DoE)-based methodology to address multifactorial problems in directed differentiation, we found instead that optimal conditions demanded BMP antagonism and retinoid input leading to induction of dorsal foregut endoderm (DFE). We demonstrate that pancreatic identity can be rapidly, and robustly, induced from DFE and that such cells are of dorsal pancreatic identity. The DFE population was highly competent to differentiate into both stomach organoids and pancreatic tissue types and able to generate fetal-type ? cells through two subsequent differentiation steps using only small molecules. This alternative, rapid, and low-cost basis for generating pancreatic insulin-producing cells may have impact for the development of cell-based therapies for diabetes.

The derivation of endoderm and descendant organs, such as pancreas, liver, and intestine, impacts disease modeling and regenerative medicine. Use of TGF-β signaling agonism is a common method for induction of definitive endoderm from pluripotency. By using a data-driven, High-Dimensional Design of Experiments (HD-DoE)-based methodology to address multifactorial problems in directed differentiation, we found instead that optimal conditions demanded BMP antagonism and retinoid input leading to ind  ...[more]
