British scientists have created human red blood cells from spare embryonic stem cells, a major breakthrough they claim could soon pave the way for production of synthetic ‘O-negative‘ blood for medical transfusions.
The red blood cells have been produced from stem cells from spare IVF embryos as part of a three-billion-pound project to develop an alternative source of O-negative blood, the universal donor group which can be transfused into people without fear of rejection, ‘The Independent’ reported.
In their research, the scientists used more than a 100 spare embryos left over from treatment at fertility clinics to establish several embryonic stem
Adult stem cell research has produced treatments for 73 different conditions, while embryonic stem cell research has not produced a single therapy or helped a single patient. But those facts were conveniently omitted from a recent column advocating increased taxpayer funding of embryonic stem cell research (“Stem cell opportunity,” Commentary, Feb. 20).
The column also neglected to mention the biggest advance in stem cell research in the last decade – the creation of induced pluripotent stem cells.
That development allows researchers to reprogram adult stem cells to behave like embryonic stem cells without destroying human embryos. It was hailed by the

Scientists have improved the sight of two people who were almost blind by injecting their eyes with stem cells from embryos.
The two women, both registered as blind, saw their vision improve in a matter of weeks after being given the embryo-derived cells in the US safety trial.
The breakthrough holds out the hope of a cure in the future for age-related macular degeneration, which currently affects some 500,000 people in Britain.
The results, published this week in The Lancet, provide a major boost for the field of stem cell reseach.

Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford’s School of Medicine. The findings were published online Monday in the Proceedings of the National Academy of Sciences.
“We’ve identified a great natural resource,” said Stanford surgery professor and co-author of the research, Michael Longaker, who has called the readily available liposuction leftovers “liquid gold.” Reprogramming adult cells to function like embryonic stem

Just as Barack Obama has loosened the regulations on embryonic stem cell research in the USA, the Austrian Commission of Bioethics (which advises the government) has decided to implement more liberal regulation. Today in Austria it is prohibited to produce embryonic stem cells, but it is allowed to import them from abroad. These cells are expensive and research is hindered by high costs. The majority of the Commission has advised, with a 17 to 5 vote, that the use of excess embryonic stem cells from assisted fertilization procedures be made legal.
