Mechanisms of assembly and remodelling of the extracellular matrix
The extracellular matrix (ECM) is the complex meshwork of proteins and glycans that forms the scaffold that surrounds and supports cells. It exerts key roles in all aspects of metazoan physiology, from conferring physical and mechanical properties on tissues and organs to modulating cellular processes such as proliferation, differentiation and migration. Understanding the mechanisms that orchestrate the assembly of the ECM scaffold is thus crucial to understand ECM functions in health and disease. This Review discusses novel insights into the compositional diversity of matrisome components and the mechanisms that lead to tissue-specific assemblies and architectures tailored to support specific functions. The Review then highlights recently discovered mechanisms, including post-translational modifications and metabolic pathways such as amino acid availability and the circadian clock, that modulate ECM secretion, assembly and remodelling in homeostasis and human diseases. Last, the Review explores the potential of ‘matritherapies’, that is, strategies to normalize ECM composition and architecture to achieve a therapeutic benefit. The extracellular matrix (ECM) is a scaffold that supports cell structure and function. This Review discusses the compositional diversity, tissue-specific assembly and remodelling of the ECM in health and disease, and explores its potential for therapeutic targeting.
