Outline of Final Research Achievements |
A new induction method using teratoma was developed. The method is transplanting human iPS cells (hiPSC) to SCID mice, sorting from teratoma cells with surface markers, and culturing. When CD34 positive cells were cultured in vascular endothelial cell medium, CD31, CD144 positive vascular endothelial cells appeared. Moreover, expression of fibroblast antigen was observed in anti-fibroblast antibody positive cells. CD56 (NCAM) positive cells after sorting were neural progenitor-like cells, and differentiated cells including neurites were observed. Thus, differentiation-induced cells could be removed by sorting hiPSC teratoma cells with cell markers. This in vivo differentiation induction method was thought to make it possible to isolate differentiated cells that are difficult to induce.
