Expression levels of core Gdf genes in pregnant rat uterus during implantation and decidualization. (A) Total RNA samples were collected from the uterus of pregnant rats on pregnant day 4.5 and subjected to RT‐PCR for the expression levels of core Gdf genes. (B) Total RNA samples were collected from the uterus of pregnant rats on pregnant day 4.5 (implantation) or ZT12 (D4.5) and D6.5 (decidualization) or ZT12 (D6.5) and subjected to RT‐qPCR. The D6.5 samples were divided into implantation sites (D6.5E) and inter‐implantation sites (D6.5). The transcript levels were calculated and normalized to each value given by the D4.5 sample. Values with different letters are significantly different (P < 0.05).
