Abstract:

To reveal the effects of interferon τ (IFN-τ) and progesterone on the expression level of extracellular matrix (ECM) and their ligands genes in bovine endometrial cells (bECs). In the study, bECs were cultured in medium containing bovine IFN-τ (bIFN-τ), progesterone and combination of bIFN-τ and progesterone, respectively, and then expression level of ECM related genes (Collagen, laminin, Fibronectin, THBS and Tenascin) and their ligand genes (Syndecan, CD44, CD47 and RHAMM) in bECs were detected by quantitative PCR after in vitro cultured bECs were treated for 24 h with bIFN-τ, progesterone, combination of bIFN-τ and progesterone, respectively. The results showed that, bIFN-τ significantly induce the expression of Tenascin, Collagen, RHAMM and Laminin, and progesterone significantly induced the expression of CD44, Fibronectin, RHAMM, and Laminin, but under co-action of bIFN-τ and progesterone, the expression level of CD44 and THBS was inhibited, and the expression of Tenascin, Fibonectin and Collagen returned to the expression level in the control group. The results suggest that bIFN-τ and progesterone might regulate the expression of ECM and their ligands in the process of embryo implantation.
