Nagy admits the promise of
personalized cell regeneration is probably too costly for mainstream use, and he believes genomic editing — in which DNA is inserted or deleted — is key to safe iPS cell implants.
Dr. Yamanaka's iPS discovery, first completed with animal
cells in 2006 and with human
cells in 2007, has since altered the fields of
cell biology and stem
cell research — opening promising new prospects for drug discovery,
personalized medicine and tissue
regeneration.
