Abstract
|
|
|
Objectives : In this study, an essential oil fragrance from Danggwi was administrated into the neural stem cell and the effect of the essential oil on the differentiation and proliferation of the neural stem cells were observed.
Methods : The establishment of the neural stem cell was identified via Nestin, DAPI dye. An essential oil fragrance from Danggwi was administrated with a proved optimum level for the survival of the cell through MTT assay. Also, according to the analysis of Western blot, the essential oil fragrance from Danggwi promotes the phosphorylating of Akt, Erk, ERM protein.
Results : MTT assay showed increased in GFAP. The result indicates that the differentiation to astrocyte is promoted. The phosphorylation levels of ERM, Erk and Akt were increased at 60 min after addition of 5 ug/ml of essential oil fragrance from Danggwi and sustained to 48 hours. These imply that essential oil fragrance from Danggwi may induce the survival and the proliferation of the differentiated cells.
Conclusions : These results suggest that the essential oil fragrance from Danggwi can be effective for the in vivo study of degenerative neuronal disease using neural stem cell.
