Dear Editor,The direct conversion of mouse fibroblasts to neurons ”1” was developed while many scientists were interested in neuronal differentiation using induced pluripotent stem cells (iPSCs) ”2”.This direct reprogramming skips a pluripotent state,making patient- and/or disease-specific cell therapy much faster and more feasible.Recent reports have indicated that mouse or human fibroblasts could be directly converted to a number of different cell types,such as cardiomyocytes,blood progenitor cells,hepatocyte-like cells,neural progenitors and specific dopaminergic neurons ”3-9”.However,all of the studies in this field have employed the retroviral or lentiviral vector delivery system.
