The metabolomic and lipidomic profiles of immature oocytes and cumulus cells within individual bovine cumulus–oocyte complexes
| dc.abstract.en | This study investigates the metabolomic and lipidomic profiles of immature bovine oocytes and their corresponding cumulus cells (CCs) within individual cumulus–oocyte complexes (COCs). Metabolomic analysis identified significant differences between the two cell types, with 62 biochemical pathways displaying differential activity, particularly in carbohydrate and lipid metabolism. Despite these metabolic differences, the lipid composition remained stable across oocytes and CCs. Notably, only four metabolites, including pantothenic acid and linoleic acid, showed significant correlations between the cell types, suggesting a potential metabolite exchange mechanism. These findings highlight the metabolic interdependence between oocytes and CCs, which is essential for supporting oocyte growth and maturation. The study provides new insights into the metabolic interactions within COCs, emphasizing the distinct yet complementary metabolic roles of oocytes and cumulus cells. Further research is necessary to explore how these metabolic dynamics change during in vitro maturation and their implications for embryo development. | |
