Induction of insulin-producing cells

摘要

What is described is a method for preparation of insulin-producing cells from non-insulin-producing cells. Mammalian fetal hepatocytes or hepatic progenitor cells are used ad the non- insulin-producing cells, and the method comprises culturing the mammalian fetal hepatocytes or the hepatic progenitor cells with 1-50 mmol/L of nicotinamide and concurrently bringing about expression of the PDX-1 gene or the NeuroD gene in the mammalian fetal hepatocytes.
