Program

Extra-cellular matrices provide the structural underpinning of human form and function. Cells comprising human tissues are embedded in, and supported by, extracellular matrices composed of collagens, proteoglycans, and associated proteins. Mineralized matrices form the basis for the skeletal system, including cartilage and teeth. Matrix scaffolds are deposited and remodeled by resident cells providing an organized milieu that in turn exerts multiple effects on cell activity, including differentiation and migration. Physiological processes including development, morphogenesis, and wound healing are associated with matrix formation and remodeling. Pathologies including atherosclerosis, metastatic invasion and rheumatoid arthritis are associated with misregulation of remodeling, whereas bone and connective tissue disorders are associated with matrix protein mutations. This symposium will bring together NIH investigators from diverse research areas who share a common interest in the extra cellular matrix and how it is remodeled.
