Abstract
The localization of vasa homolog protein in the spermatogenic cells of mice, rats, and guinea pigs was studied by immunofluorescence and electron microscopies with the antibody against mouse vasa homolog (MVH) protein. By immunofluorescence microscopy, four types of granular staining patterns were identified: (1) fine particles observed in diplotene and meiotic cells, (2) small granules associated with a mitochondrial marker and appearing in pachytene spermatocytes after stage V, (3) strands lacking the mitochondrial marker in late spermatocytes, and (4) large irregularly shaped granules in round spermatids. Immunoelectron microscopy defined the ultrastructural profiles of these MVH protein-positive granules: the first type consisted of small dense particles, the second had intermitochondrial cement (IMC), the third type, consisting of strands, had loose aggregates of either material dissociated from IMC or 70–90-nm particles, and the fourth had typical chromatoid bodies (CBs). The results suggest that MVH proteins function in these components of nuage. MVH protein-positive structures other than CBs disappeared during meiosis and CB appeared first in early spermatids. The results suggest that the formation of nuage is discontinued between spermatocytes and spermatids. The formation of nuage in spermatocytes and of CB in spermatids is discussed.
