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
In the beginning, one cell becomes two, and two become four. Being fruitful, they multiply into a ball of many cells, a shimmering sphere of human potential. Scientists have long dreamed of plucking those naive cells from a young human embryo and coaxing them to perform, in sterile isolation, the everyday miracle they perform in wombs: transforming into all the 200 or so kinds of cells that constitute a human body. Liver cells. Brain cells. Skin, bone, and nerve.

“Behind the embryonic stem cell war is just a war of patents,” led an article in the Osservatore Romano newspaper by Angelo Vescovi, a geneticist at the Niguarda Hospital in Milan and a professor at the Università Bicocca, who has always been against embryonic stem cell research and supporter of ‘law 40’ (recently declared unconstitutional by authorities).
“The production of embryonic stem cells by reprogramming adult cells discovered recently is not only better than methods that use human embryos, but is also based on new techniques, which are not protected by patents that currently govern the use of stem cells

Halfway through February, the National Swiss Fund has established a national plan for stem cell research and regenerative medicine, providing 10 million francs (6,766,000 euros) in financing over 5 years. In November, the Foundation will make a decision on projects that have already been submitted. In January 2010, those which have been approved will get underway. The objective is to favor basic biological stem cell and regenerative medicine research, and to spread awareness internationally.
At the end of 2004 in a referendum, Swiss citizens approved a law that allows the use of excess embryonic
(CBS) This week, British researchers announced another extraordinary breakthrough in medical research. They have taken stem cells from an embryo and created human sperm.
It’s very exciting, said the man who led the team. They have heads, they have tails, and they move. They have all the essential qualities for creating life. The aim, we are told, is to revolutionize the treatment of infertility.
But this discovery has created some interesting dilemmas. Sperm could be produced from female stem cells. That would mean women would no longer need men to create babies. It could also be theoretically used to produce
