Low- and middle-dose of radiation on hNPC and HUVEC

Many neural progenitor cells present in the fetus, but also in adult brain, which play a major role for the reproduction for healingin regeneration of neuronal cells, when differentiated cells are damaged. However, effects of radiation effect on undifferentiated neural progenitor cells remained unclear. The radiation doses of medical exposure, pollution by nuclear power plant accidents, and other exposure of workers; medical workers, airline crews, and astronaut have been focused. In this study, we report the effects of low- to middle- dose doses of radiation on cultured human neural progenitor cells (hNPC) differentiated derived from embryonic stem (ES) cells, which are partially compared with those of human umbilical vein endothelial cell (HUVEC).
