[Bone and Stem Cells. Regulation of chondrocyte differentiation from mesenchymal stem cells]

Chondrocytes are derived from mesenchymal stem cells and play an essential role in endochondral ossification. Transcription factors, Sox9, Runx2, Runx3 and Osterix are critical for endochondral ossification, and regulate differentiation of mesenchymal stem cells into chondrocytes, and proliferation, maturation and apoptosis of chondrocytes. Recent advances in gene cloning approaches utilizing microarray and high-throughput sequencing technologies have revealed functional regulatory mechanisms of these transcription factors and contributed to understanding of molecular mechanisms of complex and harmonious chondrocyte differentiation.
