Membrane Recycling in the Epithelium of the Seminal Vesicle Intersects the Secretory Pathway
In the epithelial cells of the seminal vesicle, as in other exocrine gland cells, exocytosis leads to the insertion of secretory granule membrane in the cell surface (Fig.la and b). As first pointed out by Palade (1959), a mechanism must exist to remove this excess of membrane in order to maintain a constant cell size. Whether the membrane to be removed would be degraded, dismantled into constituents to be subsequently reassembled, or reutilized as such, has become, since then, a matter for debate.
