Biochem/physiol Actions

Hyaluronidase degrades hyaluronan and has been found to be inappropriately regulated during cancer progression.
These enzymes randomly cleave β-N-acetylhexosamine-[1→4] glycosidic bonds in hyaluronic acid, chondroitin, and chondroitin sulfates.

Hepatocyte Culture

Hepatocytes are epithelial cells found in the liver. They perform important functions, such as helping to detoxify blood, and to synthesize transport proteins, such as lipoprotein, albumin and transferrin. Primary and secondary cultures of hepatocytes are useful for studying the mechanisms of liver regeneration and differentiation.
