Additional file 3: of Putative endothelial progenitor cells do not promote vascular repair but attenuate pericyte–myofibroblast transition in UUO-induced renal fibrosis

Figure S3. pEPCs alleviated kidney microvascular rarefaction after ischaemia reperfusion injury. Mice were subjected to ischaemia reperfusion injury (IRI) and sacrificed on day 5. CD31 staining (red) showed that endothelial cells decreased on IRI-day 5. Exogenous injection of pEPCs promoted vascular repair and reduced capillary rarefaction. The data are presented as the mean ± SD; n = 4–5/group. *p < 0.05. Scale bar, 20 μm. (TIF 8318 kb)
