Angiogenesis in the corpus luteum
The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual cycle. The molecular regulation of these diverse aspects is examined. The CL provides a unique model system in which to study the cellular and mol...
متن کاملBiology of the Corpus luteum
Corpus luteum (CL) is a small, transient endocrine gland formed following ovulation from the secretory cells of the ovarian follicles. The main function of CL is the production of progesterone, a hormone which regulates various reproductive functions. Progesterone plays a key role in the regulation of the length of estrous cycle and in the implantation of the blastocysts. Preovulatory surge of ...
متن کاملBiosynthesis of retinal in bovine corpus luteum.
Bovine corpus luteum tissue was sliced and incubated with beta-[15,15'-(3)H]carotene. The conversion of radioactive beta-carotene into radioactive retinal was substantiated utilizing column chromatography, thin-layer chromatography, high-speed liquid chromatography, and a derivative formation. Lowering of the incubation temperature to 20 degrees C or boiling the tissue eliminated the conversion...
متن کاملMicrovascular endothelial cells of the corpus luteum
The cyclic nature of the capillary bed in the corpus luteum offers a unique experimental model to examine the life cycle of endothelial cells, involving discrete physiologically regulated steps of angiogenesis, blood vessel maturation and blood vessel regression. The granulosa cells and theca cells of the developing antral follicle and the steroidogenic cells of the corpus luteum produce and re...
متن کاملImmunohistochemical localization ofsteroidogenic enzymes in corpus luteum
We analyzed the localizatien ofsteroidogenic enzymes (P450 scc, 3 B HSD, P450 arorn and P450 c17) in the corpora lutea oftwo Hokkaido sika deer (Cervus nippon oresoensis) during the early mating season. Two corpora lutea were found in each female and the timing of formation of the corpora lutea seemed diflbrent. P450 scc, and 3 B HSD, positive luteal cells were fbund in both corpora lutea. The ...
