Nonciliated cells of the rat efferent ducts endocytose testicular sulfated glycoprotein‐1 (SGP‐1) and synthesize SGP‐1 derived saposins
Abstract
Sertoli cell sulfated glycoprotein-1 (SGP-1) is a heavily glycosylated and sulfated 70 kDa protein that is secreted into the lumen of the seminiferous tubule where it binds to spermatozoa. Recent light and electron microscope immunocytochemistry has suggested that the testicular SGP-1 detaches from the surface of spermatozoa in the lumen of the efferent ducts to be endocytosed within the endocytic apparatus of the epithelial nonciliated cells. …
