Microdissection and chromosome painting of X and B chromosomes in the grasshopper Eyprepocnemis plorans.

25 Oct 2009 The relative location of 2 repetitive DNAs, i.e. ribosomal (rDNA) and a tandemly repeated satellite DNA (satDNA), with respect to the centromere, suggested that B chromosomes in the grasshopper Eyprepocnemis plorans derived intraspecifically from ... Read more...

Cohesin SMC1beta protects telomeres in meiocytes.

17 Oct 2009 Meiosis-specific mammalian cohesin SMC1beta is required for complete sister chromatid cohesion and proper axes/loop structure of axial elements (AEs) and synaptonemal complexes (SCs). During prophase I, telomeres attach to the nuclear envelope (NE), ... Read more...

Testicular gene expression profiling following 2-methoxyethanol and 2-ethoxyethanol exposure in male rats reveals abnormal expression of the actin binding protein cortactin in degenerating spermatocytes.

26 Jul 2009 The glycol ether solvents 2-methoxyethanol (2-ME) and 2-ethoxyethanol (2-EE) produce testicular toxicity characterized by spermatocyte degeneration, while a similar glycol ether, 2-butoxyethanol (2-BE), has no testicular effects. The goal of the ... Read more...

Technical information about 'Spermatocytes'

Definition: Male germ cells derived from SPERMATOGONIA. The euploid primary spermatocytes undergo MEIOSIS and give rise to the haploid secondary spermatocytes which in turn give rise to SPERMATIDS.
