Tubulobulbar complexes are finger-like structures that form at the interface between maturing spermatids and Sertoli cells prior to sperm release and at the interface between two Sertoli cells near the base of the seminiferous epithelium. They originate in areas previously occupied by actin filament-associated intercellular adhesion plaques known as ectoplasmic specializations. Actin filaments also are associated with tubulobulbar complexes where they appear to form a network, rather than the… CONTINUE READING
