ECM (Extracellular Matrix)

The extracellular matrix (ECM) is a complex network of proteins and molecules outside cells that provides structural support and helps organize tissues. Think of it as a scaffolding or glue that holds cells in place, while also facilitating communication, growth, and repair. The ECM is essential for tissue strength, flexibility, and signal transmission, playing a vital role in maintaining the health and function of organs and systems throughout the body.
