Název v původním jazyce

Organization of the expanded cumulus-extracellular matrix in preovulatory follicles: arole for inter-alpha-trypsin inhibitor.

Popis výsledku v původním jazyce

It has been shown that following endogenous gonadotropin surge, oocyte-cumulus complexes (OCC) synthesize hyaluronan (HA) in a process called cumulus expansion. During this process, HA associates with proteins and proteoglycans to form the expanded HA-rich oocyte-cumulus extracellular matrix (ECM), where the heavy chains of the serum derived inter-alpha-trypsin inhibitor family (IalphaI) bind covalently to HA. No study has been performed on the occurrence and regulation of this process during oocyte maturation in species other than mouse and pig, although, the heavy chains (of IalphaI)-HA complex was purified from human amniotic membrane. The present review pointing out that: 1/ formation of expanded HA-rich oocyte-cumulus ECM is dependent on the presence of IalphaI molecules, 2/ the heavy chains of IalphaI molecules identified in the serum are covalently linked to HA during cumulus expansion in mouse and pig, 3/ the family of IalphaI molecules can freely cross the blood-follicle barri
