The regenerative uterine horns after collagen/transfected En-PSCs transplantation. Histological structures of the regenerative uterine horns at 30 days (A–E) and 90 days (F–J) in sham group (A and F), collagen/PBS group (B and G), collagen/En-PSCs group (C and H), collagen/si-CYR61 En-PSCs group (D and I), and collagen/ov-CYR61 En-PSCs group (E and J). Arrowheads indicated repair sites. Scale bar, 500 μm. Local magnification of figures (A–J) were showed in the pictures (A′–J′). Scale bar, 200 μm. K Statistical analysis of the thickness of endometrium in the five groups. Each experiment was repeated four times. Data were presented as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001
