title: The fine structure of the swine sweat gland. I. The acini.
abstract: The structure of the acini in the swine sweat gland is described here at the TEM level. The acini of the sweat gland in the pig is formed by 2 secretory cell types: dark seromucous cells and clear cells. The dark seromucous cells are actively secretory and their secretion is apocrine. The clear cells seem to be involved in an active transport of water and electrolytes through their cytoplasms.
