Recombinant humanized type III collagen (MW 55900) is a recombinant humanized collagen protein, with a molecular weight of 55900 Da, that offers diverse biological functions, such as enhancing skin extracellular matrix regeneration and improving the cellular microenvironment. This compound inhibits the proliferation, migration, and invasion of breast cancer cells. Type III collagen plays a role in cell adhesion, migration, proliferation, and differentiation through interactions with integrins.
