Fig. 4From: Endometrial mesenchymal stromal/stem cells improve regeneration of injured endometrium in miceStromal cell proliferation and angiogenesis in mouse endometrium. (A) Representative immunofluorescent images showing the nuclear expression of Ki67 protein (green) in mouse endometrium (white arrow) at different timepoints of post-transplantation. Scale bar: 50 μm. (B) Relative Ki67 protein expression in the PBS group (blue bars) and the eMSC group (yellow bars) (n = 4). (C) Immunofluorescent staining of blood vessels in the mouse endometrium with CD31 (red, white arrows). Scale bar: 50 μm. (D) Relative number of blood vessels in the PBS group (blue bars) and the eMSC group (yellow bars) (n = 4). (E) Relative gene expression of Vegfa in the PBS group (blue bars) and the eMSC group (yellow bars) on post-operative Day 3, 7 and 14 (n = 4). Representative western blotting images (F) and quantitative analysis (G) of VEGF protein expression in the PBS group (blue bars) and the eMSC group (yellow bars) normalized to β-actin (n = 4). Results are presented as mean ± SD; *P < 0.05. Abbreviation: eMSC, endometrial mesenchymal stem cells; Vegfa, vascular endothelial growth factor ABack to article page
