Tubular 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. Magnification, ×40. huMSC human umbilical cord-derived mesenchymal stromal cell, IRI ischaemia/reperfusion injury
