Peritoneal macrophages modulate human granulosa-luteal cell progesterone production. 1985

J Halme, and M G Hammond, and C H Syrop, and L M Talbert

Macrophages have been identified in the developing corpus luteum in several species, including man, and also constitute approximately 90% of cells in the peritoneal cavity. We studied the effect of peritoneal macrophages or blood monocytes on progesterone (P) synthesis by human granulosa cells from preovulatory follicles obtained at laparoscopy of 14 women undergoing in vitro fertilization. Pooled granulosa cells from follicles with mature ova were isolated by Ficoll-Hypaque gradient centrifugation. Washed granulosa cells (0.75 X 10(5)/ml) were incubated in Dulbecco's Minimum Essential Medium containing 20% calf serum with varying concentrations of pelvic macrophages (0.8-29 X 10(5)/ml) or fresh and mature blood monocytes (0.25-2.5 X 10(5)/ml). P production was determined by RIA of medium at 24-h intervals for 24-48 h. In situ concentrations of pelvic macrophages from 8 patients with tubal infertility increased cumulative P production to 140 +/- 17.8% (mean +/- SEM) of the control values. A similar increase (182 +/- 62.7%) was found with macrophages from 6 patients with endometriosis or unexplained infertility. Both fresh and mature monocytes stimulated P production to 225% and 261% of control values, respectively. Indomethacin (10(-4) M) or monoclonal antibody to somatomedin-C did not prevent stimulation of P production. These results suggest that peritoneal macrophages may exert luteotropic effects on cumulus cells while the ovulated oocyte resides in the tube, and incoming monocytes may be important in stimulating luteal cells in the developing corpus luteum.

UI	MeSH Term	Description	Entries
D007213	Indomethacin	A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS. It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES.	Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin
D007334	Insulin-Like Growth Factor I	A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.

D008184	Luteal Cells	PROGESTERONE-producing cells in the CORPUS LUTEUM. The large luteal cells derive from the GRANULOSA CELLS. The small luteal cells derive from the THECA CELLS.

D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D009000	Monocytes	Large, phagocytic mononuclear leukocytes produced in the vertebrate BONE MARROW and released into the BLOOD; contain a large, oval or somewhat indented nucleus surrounded by voluminous cytoplasm and numerous organelles.	Monocyte
D010529	Peritoneal Cavity	The space enclosed by the peritoneum. It is divided into two portions, the greater sac and the lesser sac or omental bursa, which lies behind the STOMACH. The two sacs are connected by the foramen of Winslow, or epiploic foramen.	Greater Sac,Lesser Sac,Omental Bursa,Bursa, Omental,Cavity, Peritoneal,Sac, Greater,Sac, Lesser
D011374	Progesterone	The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
