Abstract:

BACKGROUND: The hedgehog pathway has paid an important role in the progress of chondrogenesis from bone marrow mesenchymal stem cells. However, the definite signal transduction pathway and cross-talking relationship with other common signal pathways are still poorly understood and the researches related to this field is to continue as a hotspot in the future study.
OBJECTIVE: To investigate the research progress of hedgehog signal pathway on the regulation of the chondrogenesis from bone marrow mesenchymal stem cells and the relationship between hedgehog and other signal pathways in the process.
METHODS: A computer-based online search in CNKI, PubMed and Google Scholar databases was performed using key words of “Hedgehog, IHH, SHH, bone marrow mesenchymal stem cells, cartilage, chondrogenesis” in English and Chinese, respectively. Literatures related to the process of chondrogenesis from bone marrow mesenchymal stem cells were included and 36 articles were extensively summarized for review.
RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells are currently accepted optimal cell seeds for the cartilage tissue engineering, and hedgehog is a critical signal molecule in the development of skeletal system. The IHH and SHH in hedgehog signal closely participate in controlling the processes of bone marrow mesenchymal stem cell proliferation and chondrogenesis, chondrocyte phenotype maintenance and cooperation with other common single pathways. However, the specific signal transduction mechanism and cross-talking contact with other signal pathways still need to be further studied, and it stands for the future research directions.
