produce human blood stem cells from skin, blood, of course, identical to the patient. It could be a revolutionary breakthrough for blood transfusions the discovery by scientists at McMaster University in Hamilton, Ontario, who have discovered how to make human blood from adult human skin.
The discovery, published in the prestigious scientific journal Nature , it could mean that in future patients in need of blood (during surgery, cancer treatment, a transplant or many other applications) may be transfused blood consists of cells with their own DNA.
times? According to scientists, human clinical trials could start in 2012. Mick Bhatia, scientific director of McMaster's Stem Cell and Cancer Research Institute at the G. Michael Degroote School of Medicine, and his team of researchers have also shown that the "conversion" from skin cells to blood cells is direct, does not require the intermediate step of transforming the stem cells of the skin and then turn them into pluripotent stem cells in the blood.
"We have shown that this works with the human skin. We know how it works and I think it can also improve the process, "said Bhatia. "We are at work - he added - to derive stem cells from other types of skin."
The discovery has been replicated many times over two years with human skin is that fewer young people by young people to show that it works for any age. The researchers took samples of skin and then extracted stem cells grown in the laboratory. He was then just add to stem a transcription factor, which is a protein that induces genes to "turn on" to reprogram cells directly and transform into blood cells.
