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 root system Fibrous root system A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. A fibrous root system is universal in monocotyledonous plants and ferns. The fibrous root systems look like a mat made out of roots when the tree has reached full maturity. Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30–50 m tall has a
