Nejire/dCBP-mediated control of H3 acetylation and transcriptional regulation by testis-specific Plus3 domain proteins during Drosophila spermatogenesis [PDF]
Spermatogenesis describes the development from germ line stem cells to highly specialized sperm. Drosophila melanogaster spermatogenesis is a good model system for chromatin remodelling processes as many of these processes are similar in mammals and in ...

Emi2 Is Essential for Mouse Spermatogenesis
The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2—

Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2.
In mitotic cells, establishment of sister chromatid cohesion requires acetylation of the cohesin subunit SMC3 (acSMC3) by ESCO1 and/or ESCO2. Meiotic cohesin plays additional but poorly understood roles in the formation of chromosome axial elements (AEs)

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

WNK1 is required during male pachynema to sustain fertility
Summary: WNK1 is an important regulator in many physiological functions, yet its role in male reproduction is unexplored. In the male germline, WNK1 is upregulated in preleptotene spermatocytes indicating possible function(s) in spermatogenic meiosis ...

Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n 26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy) [PDF]
The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of meiosis.

Methylation of the Gpat2 promoter regulates transient expression during mouse spermatogenesis [PDF]
Spermatogenesis is a highly regulated process that involves both mitotic and meiotic divisions, as well as cellular differentiation to yield mature spermatozoa from undifferentiated germinal stem cells.

Spermatocytic tumor (ST) is a very rare disease, accounting for approximately 1% of testicular cancers. Previously classified as spermatocytic seminoma, it is currently classified within the non-germ neoplasia in-situ-derived tumors and has different clinical-pathologic features when compared with other forms of germ cell tumors (GCTs).

Isolation and characterization of human spermatogonial stem cells
Background To isolate and characterization of human spermatogonial stem cells from stem spermatogonium. Methods The disassociation of spermatogonial stem cells (SSCs) were performed using enzymatic digestion of type I collagenase and trypsin.
