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
Fibrous joint Fibrous joint Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses. Most fibrous joints are also called "fixed" or "immovable". These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures. In fetal skulls the sutures are wide to allow slight movement during birth. They later become
