P-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 کاملThe Effect of Ligation of the Ovarian Artery on Ovarian Follicular Function in Rats
In the present study was performed to evaluate the follicular growth and hormonal changes after ovarian artery ligation in rats. Fifty six virgin 90-day–old female rats were used. The rats were chosen from 100 female rats by a vaginal smear, which showed that they were synchronized in estrous phase of the menstrual cycle. Animals were kept in seven cages (n=8 in each) at a temperature of 22 ± 2...
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 کاملDIFFERENTIATION OF HUMAN OVARIAN FOLLICULAR GRANULOSA CELLS INTO KERATINOCYTES
Background & Aims: Stem cells are undifferentiated cells and are found in different tissues. These cells have capacity of self-renewal and differentiation into other lineages. Granulosa cells (GCs) are the multipotent stem cells. In the present research we evaluated the differentiation potential of GCs into keratinocytes. Material & Methods: GCs were cultured after enzymatic isolation from ova...
متن کاملHuman ovarian theca cells are a source of renin.
Human ovarian follicular fluid contains renin-like activity. In normal women, circulating levels of prorenin, the biosynthetic precursor of renin (EC 3.4.23.15), change in parallel with changes in progesterone during the menstrual cycle. Therefore, the ovary has been implicated as a source of plasma prorenin. In the present studies, we report the finding of high concentrations of prorenin in hu...
