The ECM in mammals is composed of around 300 proteins, known as the core matrisome. Here I will discuss emerging approaches in aECM design, hopefully inspiring cell biologists to apply these systems to address their specific biological question. The extracellular matrix (ECM) is a dynamic structure that is constantly remodelled to control tissue homeostasis. Recent advances in the molecular design of ‘smart’ synthetic biomaterials have generated artificial ECM (aECM) that mimic some of the key structural and biochemical characteristics of their naturally derived counterparts and, thanks to their synthetic origin, promise to overcome some complexities of the latter. Extracellular Matrix (ECM) In biology, the extracellular matrix ( ECM ) is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells. These interactions can be studied using well-established 3D in vitro model systems such as collagen gels or Matrigel™ generated from native ECM macromolecular components. Many crucial cellular processes in our tissues are governed by complex, spatio-temporally regulated interactions between cells and their extracellular matrix (ECM). Mecham was recently awarded the Carl and Gerty Cori Faculty Achievement Award.Integration column: Artificial ECM: expanding the cell biology toolbox in 3D Integration column: Artificial ECM: expanding the cell biology toolbox in 3D In recognition of his outstanding research and contributions to Washington University, Dr. Over 40 students and fellows have trained in his laboratory and have gone on to research and teaching positions in universities throughout the world. He has extensive involvement in medical and graduate school education and has received the university’s Distinguished Teacher Award three times and the Outstanding Faculty Mentor Award. Mecham twice served as interim chair of his Department. He has held numerous national and international scientific leadership positions and has served on important review and policy committees at all levels.Īt Washington University, Dr. He is a fellow of the American Association for the Advancement of Science and has served on editorial boards of major scientific journals. (decellularized ECM, purified ECM proteins, polysaccharides. He was the first president of the American Society for Matrix Biology and has two honorary degrees from universities in Europe. Communications Biology is a broad scope open access journal that publishes high-quality research across all areas of biology. ECM degradation is captured by local fluidization of the material and permits cell migration through the ECM. Mecham has authored over 250 scientific papers and has edited 13 books. The ECM is regarded as a viscoelastic material, with or without anisotropy due to fibrillar strain stiffening, and modeled by means of the meshless Lagrangian smoothed particle hydrodynamics (SPH) method. Mecham moved to the Department of Cell Biology and Physiology at Washington University where his laboratory continues to study extracellular matrix structure and assembly.ĭr. After a sabbatical at the National Institutes of Health as a Visiting Scientist, Dr. Mecham was recruited to Washington University in 1977 in the Pulmonary Division, Department of Medicine, where his research focused on the underlying causes of emphysema and pulmonary hypertension. He continued these studies during his graduate work at Boston University School of Medicine where he earned a Ph.D. He received his Bachelor of Science degree in Biology at the University of Utah in 1973 where he developed an interest in the extracellular matrix proteins that contribute to vascular function.
