Outline of Final Research Achievements

We succeeded in isolation of non-adherent sphere-forming cell subpopulations and prolonged culture for about one year using patient-derived hepatoblastoma tissue and established hepatoblatoma cell line HepG2. We investigated whether the difference of sphere-forming cells subpopulations with cancer stem cell like properties and differentiation-inducing cells by serum stimulation is attributed to the variation of differentiational state, therefore adhesion to collagen Ⅳ coated plate, single layer proliferation, and hepatocyte molecular marker were induced.

Academic Significance and Societal Importance of the Research Achievements

肝芽腫組織サンプルからがん幹細胞様非接着性sphere 形成細胞を分離し、長期培養に成功した報告はこれまでなく、学術的意義の高いものである。また、肝芽腫がん幹細胞に特徴的な分子プロファイリングが今後さらに進み、特異的な治療標的を明らかにできれば、治療薬や治療法の開発に応用できる可能性がある。
