Insulin producing cells (IPCs) from various cell sources. (A) Overexpression of the defined exogenous transcription factors (Pdx1; Pdx1/VP16 (fusion protein) + NeuroD; Pdx1/VP16 (fusion protein) + Ngn3) in liver cells generate IPCs [53,54]. (B) IPCs could also be induced from pancreatic non-β cells such as acinar cells and α-cells by forced expression of Ngn3 + Pdx1 + Mafa and Pax4, respectively [58]. (C) Adipose tissue-derived stem cells could be differentiated into functional IPCs by transducing Pdx1 [59].
