Protective effect of HUMSCs on RILI. (a) Compared to control HUMSCs, CXCR4-overexpressing HUMSCs could attenuate histopathological changes of RILI by hematoxylin and eosin (H&E) and Masson staining of lung sections. (b) TGF-β1 protein was assessed by western blot analysis in the mouse lung tissue. (c) Densitometric quantification of TGF-β1 protein levels in the lung tissue. The radiation-induced enhancement of TGF-β1 was inhibited markedly in the CXCR4-overexpressing group compared to control group (∗∗ P < 0.01, n = 6).
