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 Scar A scar is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs and tissues of the body. Thus, scarring is a natural part of the healing process. With the exception of very minor lesions, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring. An exception to this are animals with complete regeneration, which regrow tissue without scar formation. Scar tissue is composed of the same protein (collagen) as the tissue that it replaces,
