Project description:Gene expression profiles in the bovine corpus luteum (CL) of the estrous cycle and pregnancy: Possible roles of chemokines in regulating CL function during pregnancy
Project description:The aim of the present study is to determine possible roles of chemokines in regulating bovine endometrial function during early pregnancy. A 15 K bovine oligo DNA microarray detected 344 and 1336 differentially expressed genes (>2-fold; P<0.05) in the bovine endometrium of 15 and 18 days of pregnancy compared with these days of the estrous cycle (cyclic, n=4). The expression of six chemokines, including CCL2, CCL8, CCL11, CCL14, CCL16 and CXCL10 was higher in the endometrium of early pregnancy than that in the cyclic stage.
Project description:In vitro maturation (IVM) of the oocytes is a routine method in bovine embryo production. The competence of bovine oocytes to develop into embryo after IVM and in vitro fertilization (IVF) is lower as compared to in vivo preovulatory oocytes. Cumulus cells (CC) that enclose an oocyte are involved in the acquisition of oocyte quality during maturation. Using transcriptomic approach we compared cumulus cells gene expression during IVM with that in vivo preovulatory period.
