Cytoskeletal dynamics and spermatogenesis
WebMay 1, 2011 · In the present review, we will focus our discussion largely on the actin-based cytoskeleton and the significance of actin regulatory proteins in spermiogenesis and spermiation, as well as BTB dynamics since few studies are found in the literature relating to the roles of the intermediate filament- or tubulin-based cytoskeletons in … WebApr 17, 2012 · TBCs are cytoplasmic evaginations of mature elongated spermatids. They penetrate into the surrounding Sertoli cell cytoplasm and are composed of both tubular and bulbous portions. The tube is surrounded by fine filaments of actin and the bulb is flanked by smooth endoplasmic reticulum.
