Measurement of concanavalin A induced agglutination of follicular, luteal and atretic rat granulosa cells. 1985

R K Parshad, and S S Guraya

To determine changes in the surface membrane of granulosa cells related to follicular atresia and luteinization, their agglutination behavior with Concanavalin A has been studied by quantitative spectrophotometry. As compared to the granulosa cells of normal Graafian follicles, the agglutination rate (delta A546/5 min) and final level of agglutination significantly increased in atretic and decreased in luteinized cells indicating the increase of Con A binding sites with atresia and decrease with luteinization. Treatments of granulosa cells with EDTA and trypsin enhanced agglutination of follicular and luteal cells but had no effect on atretic granulosa cells.

UI	MeSH Term	Description	Entries
D008686	Metestrus	The period following ESTRUS during which the phenomena of estrus subside in those animals in which pregnancy or pseudopregnancy does not occur.
D010424	Pentobarbital	A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011359	Proestrus	A phase of the ESTROUS CYCLE that precedes ESTRUS. During proestrus, the Graafian follicles undergo maturation.
D003208	Concanavalin A	A MANNOSE/GLUCOSE binding lectin isolated from the jack bean (Canavalia ensiformis). It is a potent mitogen used to stimulate cell proliferation in lymphocytes, primarily T-lymphocyte, cultures.
D003338	Corpus Luteum	The yellow body derived from the ruptured OVARIAN FOLLICLE after OVULATION. The process of corpus luteum formation, LUTEINIZATION, is regulated by LUTEINIZING HORMONE.	Corpora Lutea,Lutea, Corpora
D004492	Edetic Acid	A chelating agent that sequesters a variety of polyvalent cations such as CALCIUM. It is used in pharmaceutical manufacturing and as a food additive.

D004971	Estrus	The period in the ESTROUS CYCLE associated with maximum sexual receptivity and fertility in non-primate female mammals.
D005260	Female		Females
D006107	Granulosa Cells	Supporting cells for the developing female gamete in the OVARY. They are derived from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the OOCYTE in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the OVUM in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors (RECEPTORS, LH).	Cell, Granulosa,Cells, Granulosa,Granulosa Cell
