Pattern of endometrial CaBP-28k mRNA expression. Endometrial tissues were divided into 7 groups (M: menstrual phase, EP: early-proliferative phase, MP: mid-proliferative phase, LP: late-proliferative phase, ES: early-secretory phase, MS: mid-secretory phase, LS: late-secretory phase) based on the endometrial tissues classified according to the last menstrual period and histology according to the criteria of Noyes et al [32]. Uterine calbindin-D_28k mRNA expression during the menstrual cycle was examined by (A: RT-PCR; B: real-time PCR). A significant increase in calbindin-D_28k expression level was observed during menstrual cycle (^aP < 0.05 vs. M, ^bP < 0.05 vs. MP or LP).
