From: Chronic endometritis modifies decidualization in human endometrial stromal cells
Secretion of PRL and IGFBP-1 from decidualized ESCs in vitro and cell numbers. Samples with endometriosis in the CE group and non-CE group were indicated by “Endo”. a The concentration of PRL in the media of cultured ESCs evaluated by ELISA. PRL concentration is lower in CE samples than in non-CE samples (P < 0.01). b The concentration of IGFBP-1 analyzed by ELISA. The data are shown using a log scale. Lower expression of IGFBP-1 is observed in CE samples than in non-CE samples (P < 0.01). c The number of stromal cells after culture for 13 days. It is obviously higher in the CE group than in the non-CE group (P < 0.05). d The concentration of PRL in the patients with endometriosis divided into the CE and non-CE groups. The level of PRL tends to be lower in the CE group than in the non-CE group (P = 0.09). e The concentration of IGFBP-1 in the patients with endometriosis separated into the CE and non-CE groups. The concentration of IGFBP-1 is lower in the CE group than in the non-CE group (P < 0.05). f The cell number of the patients with endometriosis divided into the CE and non-CE groups. The cell numbers are not different between the CE group and the non-CE group (P = 0.11)
