The ability to generate vascular networks using HA hydrogels leads to opportunities for in vivo and clinical applications. 2016;207:125-128. CD44 mediates cell interaction with HA and the binding of the two functions as an important part in various physiologic events, such as cell aggregation, migration, proliferation and activation; cellâcell and cellâsubstrate adhesion; endocytosis of HA, which leads to HA catabolism in macrophages; and assembly of pericellular matrices from HA and proteoglycan. Semin Arthritis Rheum 2000;30(2 Suppl 1):19-25. It's not known if this benefit is due to hyaluronic acid or other ingredients.
