Human embryonic stem cells can partly restore vision in blinded rats and may offer a source of transplants for people with certain eye diseases, such as macular degeneration, researchers from Advanced Cell Technology Inc. in Worcester, Mass., reported Wednesday. The team induced embryonic stem cells to mature into retinal cells, then implanted them in rats genetically engineered to go blind. Soon the rats were able to follow lights with their eyes.

Researchers from Advanced Cell Technology Inc. in Massachusetts reported this week in the journal Lancet that they had grown human stem cells without the use of contaminating animal cells. They said their work, done outside federal restrictions, could bypass problems with existing stem cell batches, which scientists complain are contaminated by animal products and thus of no use in treating people. The finding follows similar research done by a team at the University of Wisconsin.

Harvard scientists are offering colleagues free access to 17 new human embryonic stem cell lines developed without government money, hoping to boost research that the Bush administration has tried to restrict. Stem cells are the body's building blocks that scientists believe can be coaxed into specific cells to repair organs or treat diseases. In 2001, President Bush restricted federal funding to research using existing cell lines.

British scientists have converted embryonic stem cells into sperm and used them to grow live mice, a feat that could lead to new treatments for fertility, the team reported in the journal Developmental Cell. Out of 256 attempts, seven mice resulted from the work, with six living long enough to reach adulthood. However, the animals were unusually small or large and died within five months of birth, apparently because they lacked normal controls over gene activity.

Disgraced South Korean scientist Hwang Woo Suk insisted that he had the technology to produce embryonic stem cells matched to different patients even though a panel of his peers said he lied about creating such cells, a newspaper reported. A university panel said last week that Hwang did not produce any patient-specific stem cell lines as claimed in a paper published in May in the journal Science. But Hwang stood by his work.

Harvard University plans to launch a multimillion-dollar center to grow and study human embryonic stem cells, the school announced. The center could be the largest privately funded American stem cell research project to date. It must use private funds to create new lines of stem cells because President Bush, citing ethical considerations, has limited federal funding for embryonic stem cell research to existing lines of cells.

Stem cells found deep inside hair follicles might offer a new way to treat baldness and burn victims, U.S. researchers reported Thursday. So far the cells have only been found in mice, but there is no reason to believe they do not also exist in humans, said the team at the Howard Hughes Medical Institute and Rockefeller University in New York.

Corporate researchers working outside controversial federal restraints said Thursday that they had engineered human stem cells that they believe could be used to repair eyes. The team at Advanced Cell Technology in Massachusetts worked with stem cells taken from human embryos made by a team at Harvard University, and coaxed them to form retinal cells.

Important evidence that human stem cells can be implanted and become part of muscles suggests that muscular dystrophy may yet become treatable, scientists announced. The discovery--made because of an odd biomedical coincidence--showed new cells can infiltrate a person's damaged muscles, take root and survive for years. This is what is needed, on a larger scale, to attack the inherited disease. "This says that we can get those cells recruited" into weakening muscles, said Dr.

U.S. doctors have managed to grow pig teeth in rat intestines, a feat of bioengineering they said could spark a dental revolution. Researchers at Boston's Forsyth Institute said their successful experiment suggests the existence of dental stem cells, which could one day allow a person to replace a lost or missing tooth with an identical tooth from his or her own cells. The research may signal that the days of synthetic dental implants could be numbered.
