Para conformar el complejo acrosomal, las innumerables vesiculas dispersas en el citoplasma, formadas en el complejo de Golgi, se acumulan al lado del nucleo y se fusionan para formar la vesicula proacrosomal.
3-[micro]m diameter) that we believe to be proacrosomal vesicles; two centrioles; and a short axoneme (Fig.
The most prominent feature of this phase of spermiogenesis is the large proacrosomal vesicle, one surface of which is closely associated with the plasma membrane.
In early spermiogenesis, the Golgi body secretes numerous vesicles of varying density, some of which fuse to form a proacrosomal vesicle [ILLUSTRATION FOR FIGURE 1 OMITTED], which becomes ovoid and attaches to the plasma membrane by some granular material [ILLUSTRATION FOR FIGURE 2 OMITTED].
Moreover, in our study, proacrosomal vesicle formation occurs in the spermatid stage, whereas Sousa and Oliveira (1994) report its occurrence in the primary spermatocyte.
