Generation of β cells from hPSCs

This is intended as a guide only; for full experimental details please read the reference provided.

Pagliuca et al. describe the generation of insulin-producing pancreatic β cells from human pluripotent stem cells (PSCs) in vitro in 4 - 5 weeks using a cocktail of small molecules and proteins.

Briefly, using a suspension-based culture system hESCs and hPSCs were seeded at 6 x 105 cells/ml. After 48 h and 72 h, respectively, differentiation was started by changing the media to Day media. Pancreatic β cells were generated as follows: Days 0-3: Definitive endoderm (DE) induction; Days 4-6; Generation of primitive gut tube (PGT); Days 7-13: Pancreatic specification; Days 14-27+ β cell maturation. The resulting β cells released insulin in response to glucose stimulation in vitro and following transplantation into mice.
