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
Granulation tissue cell types, most of which can be associated with one of the following functions: An excess of granulation tissue ("caro luxurians") is informally referred to as "proud flesh." The extracellular matrix of granulation tissue is created and modified by fibroblasts. Initially, it consists of a network of type-III collagen, a weaker form of the structural protein that can be produced rapidly. This is later replaced by the stronger, long-stranded type-I collagen, as evidenced in scar tissue. The main immune cells active in the tissue are macrophages and neutrophils, although other leukocytes are also present. These work to phagocytize old or
