Reducing the content of UBR4 in MenSCs-EXO would alleviate its therapeutic effect on IUA rats. (A) H&E staining of uterine tissue (Scale bar = 200 μm) (The white line indicates endometrial thickness, the black triangles indicate glands); (B) Masson staining of uterine tissue (Scale bar = 200 μm); (C) Immunohistochemical staining of CD31 (Scale bar = 50 μm) (The black arrows indicate neovascularization); (D) Immunofluorescence assays of Ki67 (red) and DAPI was used to stain nuclei (Blue). (Scale bar = 50 μm). Data were mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001 for One Way ANOVA
