1Mash1 efficiently reprograms rat astrocytes into neurons显示文摘To date,it remains poorly understood whether astrocytes can be easily reprogrammed into neurons.Mash1 and Brn2 have been previously shown to cooperate to reprogram fibroblasts into neurons.In this study,we examined astrocytes from 2-month-old Sprague-Dawley rats,and found that Brn2 was expressed,but Mash1 was not detectable.Thus,we hypothesized that Mash1 alone could be used to reprogram astrocytes into neurons.We transfected a recombinant MSCV-MASH1 plasmid into astrocytes for 72 hours,and saw that all cells expressed Mash1.One week later,we observed the changes in morphology of astrocytes,which showed typical neuronal characteristics.Moreover,β-tubulin expression levels were significantly higher in astrocytes expressing Mash1 than in control cells.These results indicate that Mash1 alone can reprogram astrocytes into neurons.Daofang Ding Leqin Xu Hao Xu Xiaofeng Li Qianqian Liang Yongjian Zhao Yongjun Wang 2014Neural Regeneration Research2014,9,1:2
