Mouse oocytes within germ cell cysts and primordial follicles contain a Balbiani body. Proc Natl Acad Sci U S A. 2007;104:187–92. 91. Guraya SS. Recent advances in the morphology, cytochemistry and function of Balbiani's vitelline body in animal oocytes. Int Rev Cytol. 1979;59:249–321...
Formation of Gametes In animals, like humans, gametes form in the gonads. In males, these are the testes. In females, these are the ovaries. Sex cells must be **haploid, meaning they contain half of the necessary genetic information. This is so two gametes can fuse together and each don...
Embryoid bodies are differentiated cell aggregates that may resemble an embryo during early development and may contain a variety of cell types (1). In the present study, however, one ESC line did produce hCG in vitro, suggesting endoderm and trophoblast differentiation. In two previous ...
The retention of a genome in mitochondria (mtDNA) has several consequences, among which the problem of ensuring a faithful transmission of its genetic information through generations despite the accumulation of oxidative damage by reactive oxygen species
chromosomes 1, 8, 13, and X was detected in sperm cell (Fig.2A). Conversely, NRapiRNA analysis showed by far that most of them mapped on chromosome 17 (Fig.2B). What is more interesting is that the mouset-complex is located on chromosome 1738, emphasizing that many major ...
These results suggest that a large number of promoters are accessible in GV oocytes, and these promoters remain accessible in MII metaphase chromosomes. Although we have no direct evidence to suggest that accessible promoters in oocytes contain components of the transcription complex, the good ...
