The scientists found a way to make blood from adult human skin.

The breakthrough finding could mean that in the future, people will need blood for surgery, cancer treatment or treatment of other diseases associated with blood such as anemia, can get the blood resulting from a piece of their own skin for transfusions. Clinical trials could begin in 2012 possible.

Mick Bhatia who is the scientific director of McMaster's Stem Cell and Cancer Research Institute in the Michael G. DeGroote School of Medicine and his team of researchers also showed that the conversion is direct. Making blood from skin does not require intermediate steps that transform stem cells or skin stem cells become pluripotent stem cells that can make many types of other human cells, then turning them into blood stem cells.
