| Research Abstract |
We used neural stem cells and skin-derived mesenchymal stem cells as pluripotent somatic stem cells to neuronal lineage. Eleven BC-box proteins(SOCS1-7, ASB3, WSB2, LRR1, VHL)-derived functional peptides are delivered to those somatic stem cells. Each peptide induced to differentiate different type of neuron. VHL and socs7-derived peptides induced to differentiate dopaminergic and motor neurons, and SOCS5-derived peptide induced to differentiate retinal color epithelial cells and gultamate neuron. This mechanism of neuronal differentiation is suggested to be related to degeradation of Stat3, but is under investigation.
