IMRCs facilitate endometrial morphological recovery and attenuate fibrosis in IUA rats. The uteri of each group were sampled and HE stained at different time intervals to measure the thickness of the endometrium and count the number of glands. (a-b) Morphological characteristics and HE staining of the uterus in each group at day 14 and 21. In HE staining, unidirectional red arrows indicate glands and bidirectional red arrows indicate endometrial thickness. Unidirectional black arrows indicate adhesion bands. Scale bars: 50 μm. (c-d) Statistical analysis of endometrial thickness at day 14 and 21. (e-f) Statistical analysis of number of glands at day 14 and 21. (g-h) Masson staining of the uterus in each group at day 14 and 21. (i-j) Statistical analysis of endometrial fibrosis at day 14 and 21. ∗p < 0.05, ∗∗∗p < 0.01, ∗∗∗∗p < 0.001, ∗∗∗∗p < 0.0001; data are represented as the mean ± SD
