Enhancing the potential of aged human articular chondrocytes for high‐quality cartilage regeneration

Autologous chondrocyte implantation (ACI) is a regenerative procedure used to treat focal articular cartilage defects in knee joints. However, age has been considered as a limiting factor and ACI is not recommended for patients older than 40-50 years of age. One reason for this may be due to the reduced capacity of aged chondrocytes in generating new cartilage. Currently, the underlying mechanism contributing to aging-associated functional...
