Glossary Collagen IV

forms part of basement membrane supporting various tissues

Collagen IV, also known as Type IV Collagen, is a crucial protein that forms part of the basement membrane, a thin layer that supports and separates cells in various tissues, including the skin, blood vessels, and organs. It provides structural support and plays a key role in tissue repair and cellular functions, making it essential for maintaining the integrity and function of these tissues.
