An Association between Mitochondria and the Endoplasmic Reticulum in Cells of the Pseudobranch Gland of a Teleost
Year: 1959
Type: article
Abstract: An elaborate and apparently unique specialization of the endoplasmic reticulum having the form of tubules and a precise orientation with respect to the mitochondria has been described for the specific cell of the pseudobranch gland. The tubules also are concentrated near the vascular border of the cell where they show continuity with the plasma membrane and open directly against the basement membrane. On the other side of the basement membrane, the endothelial cells of the sinusoid show openings or discontinuities characteristically associated with secretory cells. The pseudobranch gland is presumed to have carbonic anhydrase as one of its primary products, if not its only one, and the elaborate ultrastructure is thought to be associated with the special problems of secreting this enzyme.
