| Outline of Final Research Achievements |
In this study, we screened the cytokines which effectively enhance the proliferation of synovial mesenchymal stem cells with their multi-lineage differentiation potential sustained. We concluded IL-1b, PDGF-AA, TNFa, FGF are the candidate cytokines for this purpose. We present these results in the 31st Japanese Orthopaedic Research meeting and 89th Japanese Tissue Culture Association annual meeting. We published three papers in international academic scientific journals.(Pretreatment with IL-1β enhances proliferation and chondrogenic potential of synovium-derived mesenchymal stem cells. Matsumura E et al. Cytotherapy. 2017 Feb., Platelet-derived growth factor (PDGF)-AA/AB in human serum are potential indicators of the proliferative capacity of human synovial mesenchymal stem cells. Mizuno M, Otabe K et al. Stem Cell Res Ther. 2015 Dec., TNFα promotes proliferation of human synovial MSCs while maintaining chondrogenic potential. Mikio Shioda et al. PLoS one 2017)
