Additional file 2: of Putative endothelial progenitor cells do not promote vascular repair but attenuate pericyte–myofibroblast transition in UUO-induced renal fibrosis

Figure S2. PDGFR-β and α-SMA expression increased over time in post-UUO kidneys. (A) IF and IHC staining for PDGFR-β showed an increased number of pericytes over time in the renal interstitium. (B and C) Western blotting and qRT-PCR showed significantly increased expression of PDGFR-β and α-SMA on UUO days 7 and 14. The data are presented as the mean ± SD; n = 5/group. *p < 0.05; **p < 0.005. (TIF 19464 kb)
