Type-I interferon regulates matrix metalloproteinases clearance of the bovine endometrial spheroid.

This study investigated the effect of type-I interferon (IFN) on the expression of matrix metalloproteinases (MMPs) of the bovine endometrial stromal cells (BES) and epithelial cells (BEE). The cells were separated and purified from the caruncles and cultured in DMEM/F-12 containing 10% fetal bovine serum. Spheroids were generated by using ascorbate.

Analysis of differentially expressed genes and the promoters in bovine endometrium throughout estrus cycle and early pregnancy.

Endometrial gene expression is primarily regulated by the ovarian steroids and pregnancy recognition factors. This study was aimed to characterize differential expression genes (DEGs) in bovine endometrium together with the analysis of their promoter region. Bovine uteri at follicular stage (FS), luteal stage (LS), and implantation stage (IS) at Day 18 of pregnancy were collected.
