Basement membrane matrix

The basement membrane matrix is a thin, sturdy layer of specialized proteins and molecules located at the boundary between different tissues, such as the surface layer of the skin or the lining of organs. It provides structural support, helps organize cells, and acts as a selective barrier that controls what passes between tissues. Think of it as a foundation or scaffold that maintains tissue shape, guides cell growth, and contributes to tissue repair and development. This matrix is crucial for tissue integrity and function, playing a key role in health and disease processes.
