Fig. 4From: The synergistic effect of electroacupuncture and bone mesenchymal stem cell transplantation on repairing thin endometrial injury in ratsEffects of BMSC transplantation and EA on endometrial epithelial and interstitial cell proliferation. a Cytokeratin and vimentin protein expression in each group were detected by immunohistochemistry (× 400), with the arrow indicating the site where brown-yellow particles were deposited. b The histogram shows the endometrial cytokeratin and vimentin MOD values of the rats in each group. Bars represent the mean ± standard error (SEM); n = 10 per group. *P < 0.05, **P < 0.01Back to article page
