The ECM is primarily composed of collagen, elastin, glycoproteins, and proteoglycans.
It plays a critical role in tissue repair and regeneration by providing a scaffold for new cell growth.
The ECM influences cell differentiation and migration through biochemical cues.
Degradation of the ECM is mediated by enzymes called matrix metalloproteinases (MMPs).
Alterations in the ECM can lead to diseases such as fibrosis, cancer metastasis, and osteoarthritis.
