Some epithelial cells coexpress p-S6 with RFP, while others are stained with the p-S6 only, suggesting that pre-cystic tubules are composed of two heterogeneous subpopulations of p-S6–positive cells: one undergoes Cre recombination (autonomous component, arrowheads) and the other does not (non...
Single nephrons span the width of lobules three times. The fine structure of glomeruli, lying in rows spanning the height of the lobule, is resolved by periodic acid methionine silver (PAMS) and periodic acid Schiff's (PAS) histochemistry. Glomeruli are connected to the proximal tubule (PT) ...
