Versican other inflammatory cells) can migrate more easily through extracellular matrix that has a higher versican content. Deposits of versican are not present in normal skin but are found in the reticular dermis during keloid scarring, a condition where scar formation becomes uncontrolled and overgrowth of skin tissue occurs at the site of the wound. Versican has been shown to interact with hyaluronan and a link protein (hyaluronan and proteoglycan link protein 1; HAPLN1). Versican Versican is a large extracellular matrix proteoglycan that is present in a variety of human tissues. It is encoded by the "VCAN" gene. Versican is a
Scar Elevated corticosteroid levels are implicated in striae development. Humans and other placental mammals have an umbilical scar (commonly referred to as to a navel) which starts to heal when the umbilical cord is cut after birth. Egg-laying animals have an umbilical scar which, depending on the species, may remain visible for life or disappear within a few days after birth. A scar is the product of the body's repair mechanism after tissue injury. If a wound heals quickly within two weeks with new formation of skin, minimal collagen will be deposited and no scar will form. When the extracellular matrix
