Effect of prostaglandin producing modulators on in vitro growth of buffalo uterine epithelial cells

摘要

Studies were conducted to examine the effect of seven prostaglandin producing modulators on the in vitro growth of uterine epithelial cells in buffalo. The uterine epithelial cells isolated from slaughtered buffaloes were cultured in media containing a) Lipopolysaccaride (LPS): 0, 0.01, 0.1, 1, 10 and 100 mu g/ml, b) linoleic acid: 0, 0.01, 0.1, 1, 10 and 100 mu g/ml, c) linolenic acid: 0, 0.01, 0.1, 1, 10 and 100 mu g/ml, d) oxytocin: 0, 10, 100, 1,000, 10,000 and 100,000 nm, e) tumor necrosis factor-alpha (TNF-alpha): 0, 0.05, 0.5, 1, 2.5 and 5 nm, 0 progesterone: 0.1, 10, 25, 50, 75 and 100 nM, and g) estradiol: 0, 2.5, 5, 10, 20 and 50 nM. The control medium consisted of RPMI-1640 plus 10% bovine fetal serum. The growth of uterine epithelial were measured in terms of viability, cell number increment and monolayer formation. Results suggested that the growth of uterine epithelial cells were significantly (P < 0.05) higher in media containing 10 mu g/ml, 10 mu g/ml, 1 nm and 10 mu g/ml linoleic acid, linolenic acid, TNF-alpha and LPS, respectively compared to control and lower doses used. Progesterone, estradiol and oxytocin did not significantly (P > 0.05) increase the growth of uterine epithelial cells. In conclusion, the growth of uterine epithelial cells increased when exposed to modulators in the order of linoleic acid >= linolenic acid >= LPS >= TNF-alpha > progesterone > estrogen > oxytocin
