When applying a new silver staining technique on developing mouse spermatids, it could be shown that strong argyrophilia in the "padlock" like nucleolus of very early spermatids is confined to its fibrillar and granular component, whereas the fibrillar centre is devoid of silver. During further steps the granular component disappears together with the fibrillar centre. The last remaining nucleolar part, the silver positive fibrillar component disintegrates at the beginning of nuclear elongation… CONTINUE READING
