High Resolution Helium Ion Scanning Microscopy of the Rat Kidney
Detail from Fig. 6A showing the principal cell (PC) and an intercalated cell (IC) at higher magnification.
The apical membrane of the intercalated cell has a highly complex organization that is formed of many microplicae and membrane furrows between these structures. Bar = 1 µm. (B) Higher magnification image of the elaborate intercalated cell apical membrane microplicae showing the deep infoldings of this membrane domain. Bar = 200 nm. (C) Apical membrane of a principal cell showing surface features that may represent exocytotic or endocytotic events. These depressions were frequently seen at the base of the short microvilli - a location in which clathrin mediated endocytosis often occurs. Bar = 200 nm.
