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...

Redundancy of the effect of TGFbeta1 and beta-NGF on the second meiotic division of rat spermatocytes.

30 Jul 2009 We have previously shown that in cocultures of late pachytene/diplotene spermatocytes (PS/DS) with Sertoli cells, beta-nerve growth factor (beta-NGF) or transforming growth factor (TGFbeta1) regulates the second meiotic division by blocking ... 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.
