It is well known that oncostatin M binds and activates leukemia inhibitory factor-specific receptors while leukemia inhibitory factor cannot bind oncostatin M-specific receptors. In this study, the differential effects of oncostatin M and leukemia inhibitory factor on cell survival and decidualization of normal human endometrial stromal cells were investigated by using 8-Br-cAMP-induced decidualization assay. Oncostatin M did not affect the viable cell numbers or the prolactin release of unstimulated stromal cells. However, oncostatin M dose-dependently suppressed prolactin releases from 8-Br-cAMP-stimulating stromal cells but enhanced their viable cell numbers. Although oncostatin M significantly enhanced viable cell numbers of 8-Br-cAMP-stimulated stromal cells, it did not affect prolactin secretion from 8-Br-cAMP-induced decidualized cells. Leukemia inhibitory factor significantly enhanced viable cell numbers of 8-Br-cAMP-stimulating cells in a dose-dependent manner as did oncostatin M, while leukemia inhibitory factor did not show any significant suppression of PRL secretion from 8-Br-cAMP-stimulating cells. These results indicate that oncostatin M inhibits the 8-Br-cAMP-induced decidualization process via oncostatin M-specific receptors and that oncostatin M and leukemia inhibitory factor enhance cell survival of 8-Br-cAMP-stimulated prolactin-non-secreting stromal cells mainly via leukemia inhibitory factor receptors. Thus, oncostatin M may autoregulate human endometrial stromal cell survival and decidualization in a paracrine manner.

UI	MeSH Term	Description	Entries
D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
