Chondrogenesis and Cartilage Regeneration Strategies
Summary
Cartilage regeneration presents a formidable challenge owing to the tissue’s avascular nature and limited intrinsic repair capacity. Chondrogenesis, the process by which progenitor cells differentiate into mature chondrocytes and produce a specialised extracellular matrix, lies at the heart of emerging therapeutic strategies. Current approaches encompass cell-based therapies using mesenchymal stem cells or autologous chondrocytes, often delivered within biocompatible scaffolds that mimic the native matrix and provide mechanical support. Bioactive molecules such as growth factors and small-molecule modulators are employed to direct lineage commitment and enhance matrix deposition. Complementary techniques exploit gene delivery and ex vivo cell priming to upregulate chondrogenic transcriptional programmes before implantation. More recent advances integrate three-dimensional bioprinting and decellularised matrices to recreate zonal architecture and enable precise spatial control of cell and signal placement. Collectively, these strategies aim to restore tissue functionality, delay joint degeneration and improve long-term outcomes in osteoarthritic and focal cartilage defects.
