| Outline of Final Research Achievements |
In this study we used neural stem cells and skin-derived mesenchymal stem cells as pluripotent somatic stem cells to neuronal lineage.BC-box proteins-derived functional peptides correspoding to BC-box motif strucre[(A,P,S,T)LXXX (A,C) XXX(A,I,L,V)], showing induction activity of neuronal differentiation, are delivered to those somatic stem cells. Different BC-box motif peptides induced to differentiate different type of neuron, but two kinds of somatic stem cells differentiated to same neurons. This mechanism of neuronal differentiation is suggested to be related to blocking of binding between elongin BC & A, and inhibition of JAK2/Stat3, but is under investigation. From these results, it is considered that this study will contribute to neuronal regenerative medicine using somatic stem cells differentiated to useful neurons.
