Cartilage Regeneration
The biological process and medical techniques aimed at restoring damaged or deteriorated cartilage tissue through cellular regeneration and tissue engineering approaches.
Cartilage Regeneration
Cartilage regeneration represents a crucial frontier in regenerative medicine, focusing on restoring damaged cartilage tissue that has limited natural healing capacity. This field combines biological understanding with innovative medical techniques to address a significant challenge in modern healthcare.
Biological Background
Cartilage tissue consists of specialized cells called chondrocytes embedded within a dense extracellular matrix. Unlike many other tissues, cartilage lacks blood vessels and has minimal access to repair cells, making natural regeneration extremely limited. This unique structure presents both challenges and opportunities for regenerative approaches.
