The Cells they are using are no real pluripotent stem cells like the ones from embryos but fat cells treated to behave like stem cells. In general differentiated cells do not revert to stem cells in vivo. You have to insert certain genes to induce this, but the result is not the same as a real stem cell.
Reprogramming normal tissue cells into other types usually involves inserting new genes randomly into the genome of these cells. This process is highly mutagenic. I wonder if this is the "mixture" they mentioned in the article is some kind of viroid to insert these genes. If this is the case the patients threated with this method my end up with cancer.
