Fig. 4From: Exosome from indoleamine 2,3-dioxygenase-overexpressing bone marrow mesenchymal stem cells accelerates repair process of ischemia/reperfusion-induced acute kidney injury by regulating macrophages polarizationEffect of MSCs-Exo-IDO on renal fibrosis in IRI mouse model. A Kidney tissues were harvested from the four groups on day 28 after IRI (n = 3/group). Kidney tissues in different groups were obtained and histopathology was monitored by Masson staining. Arrowheads indicated the collagen deposition and fibrotic lesions. B Quantization diagram of panel A as shown in the right. C Western Blot was used to detect the expression of α-SMA, collagen I and collagen III in the above kidney tissues (n = 3/group). D Quantization diagram of panel C as shown in the right. The histogram is presented by Means ± SD. *P < 0.05; **P < 0.01Back to article page
