interstitial matrix
Quick Summary
The interstitial matrix is a component of the extracellular matrix found in tissues. It's a gel-like substance filling the spaces outside of cells, composed of large polysaccharide molecules suspended in interstitial fluid. This fluid contains water, inorganic salts, nutrients, and waste products.12
The interstitial matrix is synthesized by mesenchymal tissues, such as connective tissue, which binds other tissues together. Its consistency varies depending on water content, polysaccharides, and structural proteins like collagen and elastin, influencing the properties of tissues like bone, tendons, and joint spaces. Adhesive proteins, such as fibronectin, are also key components, binding matrix molecules and cell surfaces.12
