This book explores how defects in extracellular matrix (ECM) proteins, their post-translational modifications, and intracellular trafficking impact cartilage and bone integrity. It underscores the ECMs role in providing structural support, establishing morphogenetic gradients, and interacting with cell surface receptors in musculoskeletal tissues. The book delves into the structure and biology of the ECM in the skeleton, discussing skeletal disorders caused by mutations in genes associated with ECM proteins, synthesis, turnover, and signal transduction. Authored by experts who have made significant discoveries in the molecular mechanisms of skeletal disorders and are developing therapeutic strategies, this book is an invaluable research for both scientists and clinicians seeking a comprehensive understanding of this growing and exciting field. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology and the International Society for Matrix Biology.
