Spermiogenesis of Tupigea teresopolis. TEM. AÂ Early to mid-spermatid. Note the peripheral position of the NC and the heterogenous condensation of chromatin towards the margin of the nucleus. BÂ Late spermatid. Note the heterogenous chromatin condensation as well as the pC which is positioned perpendicular to the dC. CÂ Late spermatid. The centriolar adjunct material begins to form. DÂ Coiled spermatid. The centriolar adjunct material is developed as beaded lamellae around the anterior part of the axoneme
