percentage was slightly reduced at D7 for CBZ, IPR and CCK compared with control cultures.
Indeed, in one experiment she had to sacriice 125 females to obtain 30 diplotene
In Gagrella unicolor male meiosis the sex chromosomes are seen as one or two heteropycnotic bodies at early prophase I and as a heteromorphic pair from diplotene
to metaphase I; furthermore they precede the migration of autosomes at both meiotic anaphases (Sharma and Dutta, 1959).
Dspite its infancy to preserve fertility and lack of studies, ovarian tissue cryopreservation has several potential advantages, such as the presence of many primordial follicles with oocyte arrest in diplotene
of prophase of the first meiotic division, primordial follicles being theoretically less cryosensitive than mature oocyes, and preservation of the endocrinal function of the ovary.
The oocytes are arrested in the dictate stage, a prolonged diplotene
stage of the first meiotic division also known as the germinal vesicle stage.
armiger (number of analyzed diplotene
plates = 378).
Mammalian oocytes are arrested at the diplotene
stage until shortly before ovulation.
El nucleo ovocitario presenta un prominente (nucleolo y los cromosomas en configuracion diplotene
1B) and, in diplotene
, they form 10 autosomal bivalents.
1 b) appears entirely heterochromatic (positively heteropycnotic) from early diplotene
It then progresses through the first meiotic prophase, which consists of leptotene, zygotene, pachytene, and diplotene
6 [micro]m) is possible to see 4 stages of early prophase: leptotene, zygotene, pachytene and diplotene
