Stem cells

"Previous methods to create embryonic-like stem cells have used a virus to help transform adult cells into pluripotent stem cells -- cells that can develop into most other cell types. But those methods carried the risk of damaging the cell's DNA. With damaged DNA, the cells often became cancerous or led to abnormalities...

"Dr Kaji had found a non-viral method to deliver four genes in a single fragment into a cell genome. However, he couldn't figure out how to remove all trace of reprogramming from the genome. Dr Nagy's group, meanwhile, had developed a system that allowed the removal of inserted genes without leaving a "footprint," but couldn't figure out how to deliver four genes into the same part of the genome. The teams' breakthrough came when they combined their methods."
