Outline of Final Research Achievements |
Manipulating lipid biosynthesis in stem cells could be a potential approach for highly efficient directed differentiation of mesenchymal stem cells. In this study, we identified the molecular mechanisms of the proteasome-dependent degradation of Lipin1 that plays critical roles in lipid homeostasis. Our finding will provide insights into the development of novel strategies for the directed differentiation of mesenchymal stem cells through Lipin1 protein stability control.

Academic Significance and Societal Importance of the Research Achievements |
再生医療研究において間葉系幹細胞の応用が進められているが、幹細胞代謝研究領域での脂質代謝調節に焦点を当てた研究は少ない。薬理学的および遺伝学的アプローチにより脂質合成制御が幹細胞で可能となれば、効率的な細胞分化誘導のほか移植後細胞の脂肪細胞分化転換抑制にも応用可能となることから、本研究で得られた知見は高効率かつ安定的な幹細胞分化誘導法開発の基礎となると期待される。
