Sure, Zambidis' group used electroporation to deliver the genes that convert adult cells back to a stem cell. But it appears that is the only new thing that they did. The 4 genes that they delivered to revert the adult cells back to stem cells were discovered back in 2006 by Yamanaka's group. It is the 4 genes that do all the magic, and identifying those genes was the really amazing step forward in the field. Electroporation, which it looks like what Zambidis et al used, is not without problems too.
