Outline of Final Research Achievements

In this study, we focused on the fact that the surface of undifferentiated iPS cells were coated with specific glycoconjugates and GSL glycans, we established a method to detect and quantify undifferentiated iPS cells in chondrocytes using cell-specific GSL-glycan analysis by applying the Aminolysis-SALSA method.
Using quantification method by glycan analysis, we could determine the optimal conditions for use of R-17F antibody, which recognizes specific glycans of iPS cells and has cytotoxic activity. Furthermore, we transplanted the antibody-treated co-cultured cells into SCID mice and showed that no teratoma was formed.

Academic Significance and Societal Importance of the Research Achievements

GSL糖鎖解析による定量化法は、フローサイトメトリー等で必要となる事前の蛍光標識等の前処置を必要とせず、また心筋細胞等の組織に対する細胞解離の前処理を必要としない。本定量化法はiPS由来生成物の品質管理に有用である可能性がある。
未分化iPS細胞の主要な除去方法の一つは、特異的な抗体を用いたcell sortingであるが、iPS由来最終生成物のviabilityを低下させる可能性がある。本研究では、R-17Fを添加するだけで未分化iPS細胞を除去することが可能であり、cell sortingによって起こりうるリスクを回避することができた。
