Connective Tissue Matrix Components (ECM Components)

Target: ECM Components
Molecular classification: Extracellular Matrix, Structural Protein, Glycoprotein, Proteoglycan

Overview

Connective tissue matrix components comprise the non-cellular portion of connective tissues, providing structural and biochemical support. This extracellular matrix (ECM) consists of ground substance (water, proteoglycans, glycoproteins, GAGs) and protein fibers (collagen, reticular, and elastic fibers). The ECM's composition dictates tissue properties and mediates crucial biological processes like cell signaling, growth, and repair. Variations in ECM components are key to different connective tissue subtypes. The matrisome encompasses all genes encoding ECM/ECM-associated proteins, highlighting the complexity and multifaceted roles of the ECM.
