Title:
膵ホルモン産生細胞の製造法
Document Type and Number:
Japanese Patent JP5762979
Kind Code:
B2
Abstract:
The present invention provides a method of more efficiently producing pancreas cells, particularly pancreatic hormone-producing cells, a method of stably producing pancreas cells in a large amount by more efficiently inducing differentiation of stem cells into pancreas cells, a medicament containing a pancreas cells and a screening method using the cells. A method of producing pancreatic hormone-producing cells, including subjecting stem cells to the following steps (1) - (4):
(1) a step of cultivating stem cells in a medium containing an activator of activin receptor-like kinase-4,7 and a GSK3 inhibitor
(2) a step of cultivating the cells obtained in the aforementioned step (1) in a medium containing an activator of activin receptor-like kinase-4,7
(3) a step of cultivating the cells obtained in the aforementioned step (2) in a medium containing any one or more kinds selected from the group consisting of (a) retinoic acid receptor agonists, (b) at least one kind selected from the group consisting of inhibitors of AMP-activated protein kinase and/or activin receptor-like kinase-2,3,6, and BMP antagonists, and (c) inhibitors of activin receptor-like kinase-4,5,7
(4) a step of cultivating the cells obtained in the aforementioned stem (3).
