Supplementary Figure S1 Identification the integrity of isolated endometrium and decidual tissues using quantitative PCR. The typical decidualization marker genes of Dtprp (A) and Alpl (B) were determined by qRT-PCR. (C) ACTA2 mRNA levels of the smooth muscle maker gene was examined by qRT-PCR. Results were normalized to the housekeeping gene GAPDH and presented as the mean ± SD of three separate experiments, with different letters (a, b, c) indicating statistical difference (p < 0.05; one-way ANOVA and Tukey’s test).
