Effect of high O2 condition on differentiation efficiency of hiPSCs in D'Amour and Nostro protocol.
A, scheme of the D'Amour differentiation protocol and the timeline of high O2 condition. Ex-4, exendin-4; HGF, hepatocyte growth factor; IGF1, insulin-like growth factor 1. B, values are the percentage of C-peptide-positive cells/well of the cells treated with high O2 condition during three different stages. *, p < 0.05 versus corresponding control. n = 6 each. C, levels of INS gene were analyzed on day 17 of differentiation in cells treated with high O2 condition during five different stages by qPCR. *, p < 0.05 versus corresponding control. n = 7 each. D, scheme of the Nostro differentiation protocol and the timeline of high O2 condition. E, values are the percentage of C-peptide-positive cells/well of the cells treated with high O2 condition during three different stages. n = 3 each. Error bars, S.E.
