From: The therapeutic impact of human neonatal BMSC in a right ventricular pressure overload model in mice
a Histology analysis of the three groups. The thickness of the RV wall increased after PAB operation, which can be blocked by treatment with BMSCs. The arrows indicated RV wall. b–d Small arteriole density was revealed in α-SMA (b), CD 31 (c), and collagen IV (d) by immunohistochemistry. The black arrow indicates vessels in the RV wall, which was moderately increased in the PAB with the placebo injection group. Compared to the sham-operated and PAB with placebo injection groups, small arteriole density increased slightly after BMSC injection in PA overload mice
