We attempted to identify a synovial sarcoma stem cell with sphere culture. The higher expression of stemness genes, Oct3, Nanog, and Sox2 was observed in the sphere subpopulation, and higher tumorigenicity was also observed in the xeno-plantation made from sphere subpopulation. Next, we compare the gene expression profiles between sphere and non-sphere subpopulation and determined candidate genes of the stem cell marker. Using the specific antibodies and cell sorter, we divided candidate gene positive and negative subpopulation, and analyzed the difference of tumorigenicity. We conformed that candidate gene positive subpopulation possess higher tumorigenicity than negative one.In this study, we first detect synovial sarcoma stem cell and stem cell marker, and these findings play a very important role about exploitation the new therapy against synovial sarcoma.
