What it is
The matrix is a network of collagens, elastin, proteoglycans and glycoproteins that provides structure and also signals to the cells embedded in it. Composition varies by tissue, and that variation is functional.
Remodelling
The matrix is constantly degraded and rebuilt. Matrix metalloproteinases break components down; synthesis replaces them. The balance between the two determines whether a tissue accumulates or loses matrix, and much research on connective tissue concerns that balance rather than synthesis alone.
Where peptide research fits
Some peptides are studied for effects on matrix gene expression or on enzymes involved in cross-linking, several of which are copper-dependent. Work in this area is typically in cultured cells or animal models, and expression changes measured there are a long way from tissue outcomes in any other setting.
