2. Extracellular Matrix Forms diverse structures Bone Ligament Tendon Vessel Connective tissue Skin Biological processes Adhesion Mechanical support Migration Proliferation Signalling Diseases Arthritis Atherosclerosis Cancer Asthma

3. Aims How is the Extracellular Matrix organized? List of components? Organization? Functional units? How did the ECM network evolve? When did functional units arise? Associated adaptations? Are they conserved? Map known disease genes onto the functional map to understand how the ECM is involved in health and disease.
