what is connective tissue extracellular matrix composed of
Connective Tissue Supports Tissues and Organs Most connective tissues are vascularized (except cartilage). The extracellular spaces (space outside of cells) in connective tissue are referred to as the extracellular matrix. Connective tissue, therefore, is made up of cells and extracellular matrix. The extracellular matrix is composed of glycosaminoglycans and proteoglycans. It is variations in the composition of the extracellular matrix that determine properties of the connective tissue. Connective tissue is made up of: Fibrous components (collagen and elastin)
