Human Elongated Spermatid Electron Micrograph

Elongated spermatid anti-SPANXa/d antibodies gold particles were associated with both the nucleoplasmic and the cytoplasmic faces of the nuclear envelope (ne) posterior to the acrosome (a) and adjacent to the manchette microtubules (M, white arrows). Staining of the nuclear envelope was not observed underlying the developing acrosome (a, bars mark posterior aspect of acrosome) or in the region immediately posterior to the acrosomal bulbs where the nuclear envelope is closely apposed to the nucleus.

The inset shows a fold of the nuclear envelope at the posterior region of the spermatid nucleus which exhibited a concentration of gold particles indicative of SPANXa/d staining. M, manchette; N, nucleus.
