extracellular matrix

The extracellular matrix (ECM) is a complex network of proteins and other molecules that surrounds and supports cells in tissues. Think of it as a scaffold that helps maintain the structure of organs and tissues in the body. The ECM provides essential signals for cell growth, movement, and development. It also plays a critical role in wound healing and the overall functioning of cells. In short, the extracellular matrix is vital for maintaining the integrity and function of tissues, connecting cells to one another and to their environment.
