*  IDEALS @ Illinois: Coregulatory Transcription Factors and Spermatogenesis
The BTB was hypothesized to be deficient in Etv5 -/- mice, and that this was mediated by Claudin 5 (CLD5). In both Etv5-/- and W/Wnu mice, the BTB was leaky. Examination of CLD5 expression among mice of various ages and phenotypes revealed the following: both ETV5 and germ cells were necessary for seminiferous epithelial CLD5 expression; CLD5 expression was ETV5 independent in vascular endothelium; and CLD5 was expressed in both Sertoli cells and spermatogonia. Data presented here support the conclusion that Sertoli cell CLD5 has a role in BTB function, but also a non-tight junction role in spermatogonia ...

In the three animals studied the total number of chromosomes in the male is as follows :. Phascolarctus 16 (14 autosomes + XY).. Sarcophilus 14 (12 autosomes + XY).. Dasyurus 14 (12 autosomes + XY).. In the female the number of chromosomes is as follows :. Phascolarctus 16 (14 autosomes + XX).. Sarcophilus 14 (12 autosomes + XX).. In all animals dealt with in this paper the Y-chromosome is very minute in size compared with the other chromosomes; also the X-chromosome is much smaller than any of the autosomes.. Chromomeres are conspicuous during syndesis, early pachytene, and early diplotene stages.. The early pachytene stage is followed by a late pachytene stage in which the threads become diffuse and lose their capacity for taking up the stain.. Except in the early meiotic prophase the sex chromosome remains compact and deeply stained and does not thread out like the autosomes.. In all the above animals the first meiotic division is reductional, separating the X- and the Y-chromosomes, and the ...
