Extracellular Matrix (ECM)
Extracellular Matrix (ECM) — The network of proteins and polysaccharides surrounding cells that provides structural support, studied extensively with matrix-remodeling peptides like GHK-Cu.
What Is the Extracellular Matrix?
The extracellular matrix (ECM) is the network of proteins, glycoproteins, and proteoglycans that provides structural and biochemical support to surrounding cells. Collagen is the most abundant ECM protein (30% of total body protein). Multiple research peptides act on ECM biology: GHK-Cu stimulates collagen and decorin synthesis, BPC-157 promotes matrix deposition, and TB-500 facilitates matrix remodeling.
Key ECM Components
- Collagens: 28 types. Type I (skin, bone, tendon), Type II (cartilage), Type IV (basement membrane)
- Fibronectin: Cell-binding glycoprotein containing the RGD integrin recognition sequence
- Laminin: Basement membrane glycoprotein critical for cell adhesion and migration
- Proteoglycans: Decorin, aggrecan, heparan sulfate provide hydration and growth factor sequestration
