OHSU research demonstrates not all embryonic stem cells are equal; produces the world’s first primate chimeric offspring
Newly published research by scientists at Oregon Health & Science University provides significant new information about how early embryonic stem cells develop and take part in formation of the primate species. The research, which took place at OHSU’s Oregon National Primate Research Center, has also resulted in the first successful birth of chimeric monkeys — monkeys developed from stem cells taken from two separate embryos. The research will be published this week in the online edition of the journal Cell and will be

The U.S. government approved the first 13 batches of human embryonic stem cells on Wednesday, enabling researchers using them to get millions of dollars in federal funding as promised by President Barack Obama in March.
“Today we are announcing the approval of the first 13 stem cell lines,” Collins told reporters in a telephone briefing.
In March, Obama lifted restrictions on human embryonic stem cell research imposed by his predecessor, George W. Bush.
He could not lift a restriction set by Congress, called the Dickey-Wicker amendment, that forbids the use of federal money to make the
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

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.
For the first time in the United States, stem cells have been directly injected into the spinal cord of a patient, researchers announced Thursday.
Doctors injected stem cells from 8-week-old fetal tissue into the spine of a man in his early 60s who has advanced ALS, or amyotrophic lateral sclerosis. It was part of a clinical trial designed to determine whether it is safe to inject stem cells into the spinal cord and whether the cells themselves are safe (…)
