Fig. 6From: Human umbilical cord-derived mesenchymal stromal cells protect against premature renal senescence resulting from oxidative stress in rats with acute kidney injuryTubular proliferation. Representative photomicrographs of paraffin-embedded kidney sections stained histochemically for PCNA, with bar graphs showing tubular proliferation in control, IRI and IRI + huMSC rats, on D2. IRI and IRI + huMSC groups differ significantly from control group (p < 0.05). Arrows indicate positive cells.
