Researchers at an American Red Cross research laboratory in Bethesda, Md., have succeeded in greatly extending the life span of human cells grown in the laboratory, a feat that promises to shed new insight on the aging process. Researchers have long known that human cells grown in a test tube can reproduce no more than 60 times before they die from old age--that somehow the cells are genetically programmed to die after that number of generations has been achieved.

The University of Minnesota has concluded that falsified data were used in a 2001 article published by one of its researchers that suggested adult stem cells could be used as an alternative to embryonic stem cells in medical research. The school is asking that the article be retracted. An investigation into research published by Dr. Catherine Verfaillie cleared her but pointed to a former graduate student, Dr. Morayma Reyes, for altering data by adjusting brightness and contrast in images used in the article.

Researchers at UC San Diego using a gene replacement technique have taken a major step toward the development of a new form of cancer therapy. A team headed by molecular biologist Wen-Hwa Lee has for the first time converted cancer cells grown in a laboratory into healthy cells by replacing a defective gene with a normal gene.

Breaking a biological barrier once thought out of reach, scientists for the first time have apparently endowed healthy human cells growing in a dish with a quality that alchemists, explorers and mystics have vainly sought for ages: immortality. In the new research, due to be published Friday in the journal Science, the scientists genetically altered cells, enabling them to keep dividing long past their allotted life span.

Re "House Defies the President on Stem Cells," May 25: When the president on Tuesday welcomed 21 families to the White House, all with children from embryos donated by other couples, I couldn't help but see there were some people missing: those with spinal cord injuries, cancer patients and the rest who could benefit from more extensive stem cell research. Is George Bush afraid he might catch some truth? Jim Geezil Agua Dulce Embryos apparently need to be saved by George Bush and House Majority Leader Tom DeLay in order to protect the "cycle of life."

Workers at the Fukushima Daiichi nuclear power plant in Japan should have their blood stem cells collected and stored in case the workers are exposed to excess radiation and require medical treatment during the shutdown and cleanup necessitated by the magnitude 9 Tohoku earthquake and the tsunami that followed it, Japanese physicians said Thursday. Bone marrow transplants are a common treatment method for such exposures, but they can be time-consuming when a search has to be made for matching donors and the recipients then have to take immunosuppressive drugs for the rest of their lives.

Cell Genesys Inc. researchers completed successful laboratory tests of a new method for combating the AIDS virus, the company announced. A team of scientists found that immune system cells, which had been genetically programmed to seek and destroy HIV-infected cells, did the job as well as naturally occurring cells that hunt down virus-tainted cells.

The Jordanian royal palace announced that "abnormal" cells were found in sections of King Hussein's urinary tract removed during surgery at the Mayo Clinic in Rochester, Minn., last week. It did not say whether the cells were malignant. But it said that the biopsy persuaded surgeons to remove Hussein's left kidney as well.

Researchers at UC San Francisco have shown that a tiny population of cells in the brain, perhaps as few as 1,500, establish the basic rhythm of the reproductive cycle in humans. Researchers seeking to improve human fertility or birth control should thus focus on these cells, physiologist Richard I. Weiner said last week at a meeting of the Society for Neuroscience in St. Louis. The cells are called GnRH-secreting neurons because they regularly produce gonadotropin-releasing hormone.

Offering new hope for diabetics, scientists on Thursday reported the latest marvel from stem cell research: mouse embryo cells that can develop into the insulin-producing portion of the pancreas. The report from researchers at the National Institutes of Health appears today in the journal Science and raises the remarkable prospect that scientists may someday be able to grow human organs in a lab that can be transplanted into patients.
