Major Scientific Advance: Blood from Skin Without Stem Cells | LifeNews.com: "Scientists in Canada have shown that they can transform human skin cells directly into blood cells, without going through an intermediate stem cell stage. This is the first evidence for human cells of what is termed “direct reprogramming”—turning one type of cell directly into another type of cell.
The scientists repeated the experiments, published online in Nature on Sunday, several times using human skin cells from young and old volunteers, to show that the process works no matter the age of the person.
