ELECTRON MICROSCOPIC OBSERVATIONS ON THE COLLAPSED AND DISTENDED MAMMALIAN URINARY BLADDER

Abstract:

Transitional epithelium from the urinary bladder of mice, rats, rabbits and dogs was studied with the electron microscope to determine the normal ultrastructure. An elaborate infolding of the two opposing cell walls was observed in the collapsed bladder. This along with grossly visible folding of the entire epithelium could greatly increase the effective cell surface when unfolded and when the cell is flattened and elongated. Desmosomes were observed indicating that these cells are strongly attached to each other, precluding any sliding movement between cells.
