We report that iPS cells can be safely and effectively generated from fresh human cord blood (CB) cells with Sendai virus (SeV) vector carrying reprogramming factors OCT3/4, SOX2, KLF4, and c-MYC. The SeV vector is a single strand RNA virus having no DNA phase, and selectively infects the freshly isolated CD34+ CD45low+ fraction of CB cells corresponding to hematopoietic progenitors. Approximately twenty ES cell-like colonies emerged from 1 x 104 freshly isolated CD34+ CB cells around 18 days after SeV infection and were selected for passage to reduce the frequency of the remaining SeV-infected cells. The complete elimination of viral constructs was confirmed after several passages by immunostaining with monoclonal antibody against hemagglutinin-neuraminidase (HN) and by RT-PCR analysis. Five ES cell-like clones were selected to examine their in vitro potential for three germ layer differentiation and their capacity for teratoma formation. Generation of non-integrating Sendai virus (SeV) iPS cells from CB cells may be an important step to provide allogeneic iPS cell-derived therapy in the future.
