IMRCs are superior to UCMSCs in repairing endometrial tissue structure and function. (a) HE staining of the uterus in IMRCs group and UCMSCs group at day 28. In HE staining, unidirectional red arrows indicate glands and bidirectional red arrows indicate endometrial thickness. Scale bars: 50 μm. (b) Matson staining of the uteri to assess the extent of fibrosis in IMRCs group and UCMSCs group at day 28. Scale bars: 50 μm. (c-d) Statistical analysis of endometrial thickness and number of glands. (e) Statistical analysis of endometrial fibrosis. Comparison of different treatments for improvement of fertility in IUA. (f) Embryo implantation in the different groups on day 15 of gestation. (g) Embryo implantation rate in each group. (h) The number of embryo implantation in each group at E15. ∗p < 0.05, ∗∗∗p < 0.01, ∗∗∗∗p < 0.001, ∗∗∗∗p < 0.0001; data are represented as the mean ± SD
