Stem Cells

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.

Working with mice, Pennsylvania researchers have isolated and grown stem cells that produce sperm, a feat that will allow them to produce massive numbers of sperm cells for research. The feat, reported in the Proceedings of the National Academy of Sciences, is important because it will allow scientists to modify the sperm genetically, correcting genetic defects or introducing desirable traits.

Using stem cells from umbilical cord blood and bone marrow, researchers have apparently cured a fatal genetic disease in a 2-year-old Minneapolis boy, which could open the door for other stem cell treatments. For the first time in his life, Nate Liao is wearing normal clothes, eating food that has not been pureed, and playing with his siblings. "Nate's quality of life is forever changed," said Dr. John Wagner of the University of Minnesota Medical School, who performed the treatment.
