Effects of renal cell transplantation on cell proliferation. Significantly higher expression of proliferating cell nuclear antigen (PCNA) and less apoptosis were seen in kidneys from rats that received SAA-expressing (vs. control) cells. A: representative images stained with anti-PCNA, Texas red secondary antibody, and 4′,6-diamidino-2-phenylindole to label all nuclei. B and C: quantification of PCNA-positive (B) and apoptotic (C) nuclei. Forty-three images were evaluated. *P < 0.05 vs. SA; §P < 0.05 vs. IA.
