Fig. 6From: Putative endothelial progenitor cells do not promote vascular repair but attenuate pericyte–myofibroblast transition in UUO-induced renal fibrosispEPCs lessened UUO-induced renal epithelial cells arrested in G2/M. Increased PH3-positive renal tubular epithelial cells (yellow arrow: the brown cell with dotted nucleus) were found in UUO-induced kidney injury. In the UUO+pEPCs group, the number of G2/M-arrested cells decreased. Data are counted as the mean ± SD, n = 5/group. *p < 0.05; **p < 0.005. Scale bar, 20 μmBack to article page
