Reproductive Biology and Endocrinology (2022) 20:172 Fig. 3 Quantitative assessment of BMSCs transplantation time. A (a): The normal uterine morphology of a rabbit; (b): Morphology of rabbit uterus after mechanical and infectious double injury; (c): Morphology after one week of injury). B Western blot was used to detect the protein expression of fibrosis markers (N‑cadherin, Collagen I, TGF‑β1, α‑SMA) at different time points. *p < 0.05. The explanation for the cropping of gels and blots in the experiment is as follows: the same proteins were separated by electrophoresis and transferred to PVDF membrane. According to the different molecular weight of the target antibody, the protein on a PVDF membrane was cropped horizontally. Then, the corresponding antibody was incubated and exposed, and the position of antibody was indicated by protein marker to ensure the exclusion of interference from non‑specific antibody magazines Fig. 4 Evaluation of the effect of BMSCs combined with estrogen on endometrial morphological recovery. A HE staining was performed to detect the endometrial glands in each group at different time points (× 100, scale bar = 100 μm). B Masson staining was performed to detect intrauterine fibrosis changes in each group at different time points (× 100, scale bar = 100 μm). C Statistical results of changes in the number of endometrial glands. D Statistical results of intrauterine fibrosis changes after endometrial damage. *p < 0.05, **p < 0.01, ***p < 0.001 (See figure on next page.) Page 3 of 3 Yuan et al.
