Localization of miR-486-5p in the rat kidney cortex 24 h post-IR, with injection of miR-486-5p (0.5 mg/kg, IR+miR-486-5p) or scramble miRNA (0.5 mg/kg, IR+scb) at the time of reperfusion. At 24 h, enhanced miR-486-5p signal (pink-red areas) was observed in rats injected with miR-486-5p, localized to proximal tubular cells (arrow) and endothelial cells (asterisk). Background nuclear staining with hematoxylin. Scale bar = 10 µm, magnification ×1000. The graph shows the quantification of miR-486-5p probe copies/field of view (++++P<0.0001 vs all groups)
