In particular, numerous premeiotic
and meiotic genes (Tab.
2010), whereas nucellus of Taxus is premeiotic
The transcription factors such as DDX4 were expressed in post-migratory primordial germ cells until the premeiotic
stage of germ cells.
Developmental expression of the pluripotency factor sal-like protein 4 in the monkey, human and mouse testis: restriction to premeiotic
Leydig cell-derived heme oxygenase-1 regulates apoptosis of premeiotic
germ cells in response to stress.
Lack of UCHL1 decreased apoptosis rate and increased the number of premeiotic
germ cells in immature mice (13), but in adult mice spermatogenesis was damaged by spermatogonial reduction and primary spermatocytes which mainly undergo apoptosis (13).
Characterization of a premeiotic
germ cell-specific cytoplasmic protein encoded by Stra8, a novel retinoic acid-responsive gene.
Dubois et al  observed in a cartilaginous fish Squalus a stimulatory effect of insulin and IGF-I on DNA synthesis in premeiotic
stages of proliferation of male germ cells.
in spermatogonia or after the completion of premeiotic
DNA synthesis (Henderson 1988).
We first investigated the effects of Cd on premeiotic
female fetal germ cells and measured germ cell apoptosis, then analyzed the effects of Cd on the development of testicular germ cells.
1] plants especially during premeiotic
stages is further known to enhance crossing over in proximal region adjacent to the centromere resulting in further enhancing the genetic variability in [F.
However, we detected heteropycnosis only during premeiotic
