INTEGRATED BIOLOGY of EXTRACELLULAR MATRIX, CELLS and PROTEASES in MORPHOGENESIS and HUMAN DISORDERS
Extracellular matrix (ECM)is the inanimate material that surrounds cells and provides the scaffold for tissue and organ architecture. It has a complex, exquisitely well-designed architecture and it provides the basis for existence of multicellular organisms.
We take a discovery-oriented approach using an integrated analysis of ECM and cells to obtain a fundamental view of human biology. Our work has a focus on mechanisms of ECM assembly and turnover and their effects on cell behavior. We investigate the molecular basis of birth defects affecting the neural tube, eyes, face, limbs, heart and blood vessels. Our research is relevant to several inherited connective tissue disorders such as Marfan syndrome and to acquired disorders such as aortic aneurysms, arthritis, cancer and glaucoma. The technology platforms employed in the laboratory include biochemistry, cell biology, proteomics and genetics.
Brief Bio-data and Research Support:

An international team of researchers, including scientists from Lerner Research Institute, has uncovered new loci (chromosomal regions) associated with heart function and development.
Rates of fetal and maternal morbidity and mortality in the United States are on the rise. A new Cleveland Clinic study shows how abnormal accumulation of extracellular matrix (ECM) prevents smooth muscle cells (SMCs) in the uterus from properly contracting, which can cause prolonged or arrested delivery and lead to poor health outcomes.
