(F) Assay of Tcf7l1 and FoxA2 mRNA by RT-PCR in cMyc null/nMyc heterozygous cells (C-/-;N+/-) and floxed parental cells (cMycfl/fl;nMycfl/fl (control)) at day 3 of differentiation in the presence or absence of 3 µM CH. Average and SD of four or six independent experiments. Tcf7l1 *p=0.01, FoxA2 *p=0.034.
