Comparison of leptin and leptin receptor gene expression between utero-placental and inter-placental uterine sections. Relative gene expression of leptin (A) and leptin receptor (B) between utero-placental and inter-placental uterine sections at post-implantation and at mid-gestation. RGE: relative gene expression. Bars and whiskers present the geometric mean and the deviation factor, or the mean and standard deviation of observed data in case of mid-gestation leptin receptor gene expression. Bars with different superscripts within the same pregnancy stage differ at P = 0.003 (post-implantation) and P = 0.043 (mid-gestation).
