| Outline of Final Research Achievements |
Platelet rich plasma (PRP) and cryoprecipitate induced chondrogenesis and cell growth into un-differentiated chondrocytic cell line ATDC5 and human mesenchymal stem cells (MSC). This data has shown a possibility that cryoprecipitate will be applicable for cartilage regeneration medicine as well as PRP. SOX6 and SOX9 played important roles on in vitro chondrogenesis induced by PRP or cryoprecipitate. PDGFβ was also identified as a causal molecule of cartilage differentiation and cell growth induced by PRP. We found that EMX1 and EMX2 were induced by SOX6 and SOX9 and could induce cartilage differentiation into ATDC5 and MSC.
