Blastogenic responses and production of TCGF by mononuclear cells isolated from the bovine endometrium

Abstract

Mononuclear cells (MNCs) were isolated from the endometrium of cattle by enzymatic digestion followed by centrifugation on a density gradient. Of the cells isolated, 32±3.2% rosetted AET-treated sheep red blood cells, 9±0.4% possessed surface membrane immunoglobulin, and 15±6.1% were esterase positive. The cells possessed the ability to proliferate in the presence of T cell mitogens and produced T cell growth factor (TCGF) after in vitro stimulation with Concanavalin A. Endometrial MNCs did not appear to suppress the blastogenesis of peripheral blood MNCs.
