Loss of BMAL1 in ovarian steroidogenic cells results in implantation failure in female mice.
The circadian clock plays a significant role in many aspects of female reproductive biology, including estrous cycling, ovulation, embryonic implantation, onset of puberty, and parturition. In an effort to link cell-specific circadian clocks to their specific roles in female reproduction, we used the promoter that controls expression of Steroidogenic Factor-1 (SF1) to drive Cre-recombinase-medi...
متن کاملHeterogeneity of Ovarian Theca and Interstitial Gland Cells in Mice
It has been established that two developmentally and functionally distinct cell types emerge within the mammalian testis and adrenal gland throughout life. Fetal and adult types of steroidogenic cells (i.e., testicular Leydig cells and adrenocortical cells) develop in the prenatal and postnatal period, respectively. Although the ovary synthesizes steroids postnatally, the presence of fetal-type...
متن کاملP-25: Characterization of Sheep Ovarian Multipotent Theca Stem Cells
Background Theca cells play important roles during folliculogenesis. They synthesize androgens, provide crosstalk with granulosa cells and oocytes during development, and provide structural support of the growing follicle to produce a mature and fertilizable oocyte. In children patients who are going to be ovariectomy, follicogenesis is at early stage and thus the follicles need to be mature in...
متن کاملConditional ablation of macrophages disrupts ovarian vasculature
Macrophages are the most abundant immune cell within the ovary. Their dynamic distribution throughout the ovarian cycle and heterogenic array of functions suggest the involvement in various ovarian processes, but their functional role has yet to be fully established. The aim was to induce conditional macrophage ablation to elucidate the putative role of macrophages in maintaining the integrity ...
متن کاملRunx3 transcription factor regulates ovarian functions and ovulation in female mice
We previously demonstrated that the Runx3 transcription factor is expressed in the hypothalami, pituitaries, and ovaries of mice, and that Runx3 knockout (Runx3-/-) mice are anovulatory and their uteri are atrophic. Runx3 mRNA expression was detected in the granulosa cells of ovarian follicles, and in the anteroventral periventricular nucleus (AVPV) and arcuate nucleus (ARC). In the present stu...
