Fig. 4From: Progenitor-like cells derived from mouse kidney protect against renal fibrosis in a remnant kidney model via decreased endothelial mesenchymal transitionMKPC injection decreases the recruitment of inflammatory cells and promotes proliferating tubule cells in five-sixths nephrectomized mice. a–j Representative photomicrographs illustrate F4/80 and α-SMA expression in the renal tissue of mice receiving saline or MKPC 14 and 17 weeks after five-sixths nephrectomy. Lower numbers of F4/80-positive cells a–e (arrow) and α-SMA-positive cells f–j (arrow) accumulate in the interstitium of mice treated with MKPCs compared with those injected with saline. k–m Ki67-positive cells (arrow) are more frequently found in the cortical tubules in mice receiving MKPC injection 14 weeks after chronic kidney injury. Scale bar: 50 μm. *P <0.05, MKPC-treated vs. saline-treated group.
