extracellular matrix (ECM)

The extracellular matrix (ECM) is a network of proteins and molecules that provides structural support and organization to tissues outside cells. It acts like a scaffold, helping cells stay in place, communicate, and perform their functions effectively. The ECM also influences cell growth, repair, and differentiation. Composed of elements like collagen, fibers, and complex carbohydrates, it varies between different tissues, such as skin, bones, and blood vessels. Overall, the ECM is essential for maintaining tissue integrity, enabling development, and facilitating healing within the body.
