This book provides a comprehensive overview of cartilage structure, functions, and approaches for the regeneration of cartilage tissue. It reviews multiple signaling pathways that are involved in the growth and repair of cartilage tissue. The initial chapter of the book examines the etiology, diagnosis, and pathological features of various cartilage diseases. Subsequently, the book presents recent advances in biomaterial sciences, regenerative medicine, and fabrication technology for cartilage regeneration. It discusses hydrogels as a promising scaffold for cartilage tissue engineering, focusing on recapitulating microenvironments present during development or in adult tissue to induce the formation of cartilaginous constructs with biochemical and mechanical properties of native tissue. Lastly, it covers the applications of 3 D printing techniques for the fabrication of scaffolds for cartilage tissue regeneration for the production of biological implants capable of treating a range of conditions.
