Concurrent Symposia Session III<br />

Natcher Conference Center<br />

Conference Room D<br />

Matrix biology and matrix remodeling<br />

Chair: Keir Neuman, NHLBI<br />

Wednesday, October 10, <strong>2012</strong><br />

2:00 p.m.–4:00 p.m.<br />

Extra-cellular matrices provide the structural underpinning of human form and function.<br />

Cells comprising human tissues are embedded in, and supported by, extracellular<br />

matrices composed of collagens, proteoglycans, and associated proteins. Mineralized<br />

matrices form the basis for the skeletal system, including cartilage and teeth. Matrix<br />

scaffolds are deposited and remodeled by resident cells providing an organized milieu<br />

that in turn exerts multiple effects on cell activity, including differentiation and migration.<br />

Physiological processes including development, morphogenesis, and wound healing are<br />

associated with matrix formation and remodeling. Pathologies including atherosclerosis,<br />

metastatic invasion and rheumatoid arthritis are associated with misregulation of<br />

remodeling, whereas bone and connective tissue disorders are associated with<br />

matrix protein mutations. This symposium will bring together <strong>NIH</strong> investigators from<br />

diverse research areas who share a common interest in the extra cellular matrix and<br />

how it is remodeled.<br />
