Protein Matrix

Meaning

The Protein Matrix refers to the complex, three-dimensional structural network of protein fibers and associated molecules that provides mechanical support and organization to tissues, particularly in the extracellular space. This matrix, rich in collagen, elastin, and various glycoproteins, is fundamental to the structural integrity of bone, cartilage, and skin, and its maintenance is highly dependent on anabolic hormonal signaling. The integrity of the protein matrix is a key biomarker for tissue longevity and resilience.
