Localization of BrdU-retaining cells by staining with the DAB lectin in 8-week-old mouse kidneys. a In the cortex, most of the BrdU-retaining cells were located among the tubular cells, and a few of them were scattered in renal interstitium; b Localization of BrdU-retaining cells in the medulla; c BrdU-retaining cells on the renal papilla; d Quantitative analysis of BrdU+ LRCs located in pairs (solid arrows) and BrdU+ LRCs revealed nuclear fragmentation and disassembly (dotted arrows, magnification × 400).
