| Outline of Final Research Achievements |
In this study, we examined the new method for direct reprogramming of adult somatic cells into different cell type by changing environment around cells without gene transfection of transcriptional factors. As a result, mouse osteoblastic cells cultured under the neural conditioned medium were induced transdifferentiation into neural cells. These cells expressed some proteins related neural cells. Moreover, to elucidate the possibility that these cells could be use as the cell source for regenerative medicine of spinal cord, these cells were transplanted with mouse spinal cord injury model. As a result, recovery of motor function of hind limbs was confirmed. Moreover, it is indicated that these cells could produce/secretion some neurotrophic factors. From these findings, it is suggested that adult somatic cells could be a source of regenerative medicine without gene transfection.
