Inter-α-Inhibitor Impairs TSG-6-Induced Hyaluronan Cross-Linking [PDF]
, 2013 Under inflammatory conditions and in the matrix of the cumulus-oocyte complex (COC), the polysaccharide hyaluronan (HA) becomes decorated covalently with heavy chains (HCs) of the serum glycoprotein inter-α-inhibitor (IαI).

PTX3 plays a key role in the organization of the cumulus oophorus extracellular matrix and in in vivo fertilization [PDF]
, 2004 PTX3 is a prototypic long pentraxin that plays a nonredundant role in innate immunity against selected pathogens and in female fertility. Here, we report that the infertility of Ptx3-/- mice is associated with severe abnormalities of the cumulus oophorus
