Quantitative RT–PCR-based expression profiling of the following genes in glucose-sensitive insulin-secreting beta-like cells differentiated by the lineage-control network: (a) the key pancreatic beta-cell-specific transcription factors Glis3, MafA, MafB, Mnx1, NeuroD, Pax4, Pdx1 and Nkx6.1, (b) the glucose- and insulin-processing factors Gck, Glut2, G6pc2, Pcsk1, Pcsk2, Slc30a8, Snap25, Stx1A, Stxbp1, Syt4, (c) the channels essential for the secretion of insulin such as Abcc8, Cacna1D, Kcnk1/3 and Kcnj11 and (d) the human islet peptide hormones Chgb, Ghrelin, Glucagon, Iapp, Insulin and Somatostatin, and (e) immature as well as mature human pancreatic beta-cell markers Acox2, Ck19, Dpp4, FoxA1, Fzd2, Gcgr, Irx2, Mmp2, Onecut2, Sftpd and Ucn3.
