MSCs ameliorate renal injury induced by AA-I. Images of Sirius red staining (a) and Masson’s trichrome staining (b) show different grades of tubular injury at week 8 in sham+saline, Sham+MSCs, AAN + saline, and AAN + MSCs mice. After the MSC treatment, the area of deposition in AAN-MSC mice was significantly smaller than that in AAN-saline mice. Data are presented as the means ± SEM (n = 8). Scale bar = 400 μm. *P < 0.05 for the comparison between AAN-saline and AAN-MSC mice
