First U.S. stem cells transplanted into spinal cord

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 (…)

Scientists Create Stem Cells From Eggs Of Aging Mice

Researchers at NYU Langone Medical Center have created stem cells from the eggs of aging mice that could be used for reproductive purposes and regenerative medicine. The study, published in April issue of Aging Cell, found that even though the eggs from older females were slightly less efficient at making stem cells than those from younger females, the capacity to create stem cells was sustained.

A process which involves removal of a stem cell from a human embryo at the blastocyst stage, entailing the destruction of that embryo, cannot be patented

The use of human embryos for therapeutic or diagnostic purposes which are applied to the human embryo and are useful to it is patentable, but their use for purposes of scientific research is not patentable

Mr Oliver Brüstle is the holder of a patent, filed on 19 December 1997, which concerns isolated and purified neural precursor1 cells produced from human embryonic stem cells used to treat neurological diseases. According to the information supplied by Mr Brüstle, there are already clinical applications, particularly for patients suffering from Parkinson’s disease.

On application by Greenpeace e.V., the Bundespatentgericht (Federal Patent Court, Germany) ruled that

Italy – top court changes strict fertility rules

Italy’s Constitutional Court relaxed parts of a law on artificial procreation that had imposed strict rules for fertility treatments.
The judges struck down as unconstitutional one of the most contested sections of the 2004 law, which said only three embryos could be created at one time, and all had to be implanted in the patient’s womb, a court spokesman said.

The judges also introduced stronger wording to ensure that embryos are implanted only if it doesn’t endanger the woman’s health, said spokesman Giovanni Gattarino.
The issue had been put before the constitutional judges by lower administrative and civil

In muscle stem cells age matters

CHICAGO (Reuters) – A new understanding of the genes that make muscle cells may change the way researchers think about stem cell transplants for muscular dystrophy and muscle injuries, U.S. researchers said on Wednesday.

In a surprise finding, they said genes important for forming muscle cells in embryos and newborns are not normally active in adult stem cells.
And researchers hoping to use muscle stem cells in stem-cell transplant therapies should not assume genes that control early muscle development serve the same purpose in repairing adult muscle, Christoph Lepper and colleagues at the Carnegie Institution in Baltimore
