Tubular Epithelial Vacuolar Change
Tubular Epithelial Vacuolar Change

Electron micrograph of proximal tubular epithelial cells showing cytoplasmic membrane bound vacuoles.
Substances in the lumen (L) can be reabsorped into tubular cells by pinocytotic vesicles which can then fuse with endogenous lysosomes to produce large membrane bound vacuoles.
Note the apical brush border or microvilli (Mv).
Tubular basement membrane (TBM).
