The forbidden doubling: exploring rare spermatocyte polyploidy in mammals [PDF]

Comparative Cytogenetics
We first studied several rare cases of over-diploid spermatocyte emergence using advanced immunocytochemical methods and a cross-species approach in subterranean rodents Ellobius tancrei (Blasius, 1884), E. alaicus Vorontsov et al., 1969, E.

The Application of Single-Cell RNA Sequencing in Mammalian Meiosis Studies

Frontiers in Cell and Developmental Biology, 2021
Meiosis is a cellular division process that produces gametes for sexual reproduction. Disruption of complex events throughout meiosis, such as synapsis and homologous recombination, can lead to infertility and aneuploidy.

Identification of fish spermatogenic cells through high-throughput immunofluorescence against testis with an antibody set

Frontiers in Endocrinology, 2023
Image-based identification and quantification of different types of spermatogenic cells is of great importance, not only for reproductive studies but also for genetic breeding.

Rbp4-Gal4, a germline driver that activates in meiosis, reveals functions for VCP in spermatid development

Fly, 2023
Valosin-containing protein (VCP) is a versatile and ubiquitously expressed AAA+ ATPase that regulates multiple stages of Drosophila spermatogenesis. While VCP has documented roles in mitotic spermatogonia and meiotic spermatocytes, it is also highly ...

Two bromodomain proteins functionally interact to recapitulate an essential BRDT-like function in Drosophila spermatocytes [PDF]

Open Biology, 2015
In mammals, the testis-specific bromodomain and extra terminal (BET) protein BRDT is essential for spermatogenesis. In Drosophila, it was recently reported that the tBRD-1 protein is similarly required for male fertility.

Differing requirements for Augmin in male meiotic and mitotic spindle formation in Drosophila [PDF]

Open Biology, 2014
Animal cells divide using a microtubule-based, bipolar spindle. Both somatic, mitotic cells and sperm-producing male meiotic spermatocytes use centrosome-dependent and acentrosomal spindle-forming mechanisms.

Spermatocytic Seminoma

Archives of Pathology & Laboratory Medicine, 2009
Abstract Spermatocytic seminoma is a rare germ cell tumor distinct from classical seminoma, both clinically and pathologically. It affects older men, has not been associated with a history of cryptorchidism, and has no known counterpart in ovary or any other site.
