Number of secondary spermatocytes is significantly decreased and spermatids are almost absent in iDKO samples. (B) UMAP projection and relative cell numbers for spermatogonia and primary spermatocytes ...

Spermatogenesis comprises mitosis for renewal of spermatogonial cells and meiosis I, followed immediately by meiosis II to form haploid round spermatids. Spermatids then undergo a process known as ...

2020). For this purpose, factors essential for spermatogenesis specifically expressed in spermatocytes and spermatids but not in spermatogonia are promising candidates. The datasets presented in this ...

One involves viruses entering the testes, where they attack spermatogonia, or cells that develop into sperm. The other involves high fever exposing the testes to heat and thereby killing sperm.

Here we provide evidence that in the Drosophila testis, connectivity serves as a mechanism that confers to spermatogonia a high sensitivity to DNA damage. We show that all spermatogonia within a cyst ...

Taken together, these results suggest that H4V is intensely expressed in spermatogonia through approximately Step 8 of spermatids, whereas H33C starts to be detected around Step 11, and remains ...
