QPCR validation of microarray data of gene expression in hESFnonendo and hESFendo decidualized in vitro with 0.5 mm with 8Br-cAMP for 96 h, expressed as fold change to the expression in 96 h vehicle controls. *, Significance accepted at P ≤ 0.05 (Mann-Whitney test). Error bars, ±sem. FC, Fold change; SST, somatostatin; CXCR4, C-X-C chemokine receptor type 4.
