Stem Cells Made Without Destroying Embryos

Posted Jan 10, 08 5:43 PM CST in Science & Health 

(Newser) – Scientists have created new embryonic stem cells while keeping the donor embryos intact, Wired reports, a breakthrough that could finally permit long-delayed research into curing cancer, heart disease, and Alzheimer’s. Researchers plucked single cells from 2-day-old human embryos, coaxed them to become ESCs, and developed them into heart tissue, neurons, cartilage, and blood cells.

The process, called blastomere biopsy, promises to be superior to November’s skin-cell watershed, which created near-equivalents of ESCs from skin cells—though they aren't as powerful and can turn cancerous. The development could finally overcome ethical objections that led President Bush to ban federal funding of ESCs in 2001, but its 80% survival rate for donor embryos may still rankle pro-life advocates.

    UK Approves Research on Human-Animal Embryos British legislators have voted to allow scientists to create hybrid human-animal embryos for stem cell research, the Daily Telegraph reports. The new laws will give British scientists more freedom to pursue hybrid research than those of any other country. The vote passed by a huge margin after supporters of the research argued that it could someday save millions of lives. More »

    Human-Animal Embryos Created In a brave new world breakthrough, British scientists for the first time have created animal-human hybrid embryos, the London Times reports. The nuclei of cow eggs were removed and replaced with ones from a human cell, creating "admixed" embryos—or "cybrids" whose genetic material is 99.9% human. Electricity jolted the cybrids to life and they survived for three days. The research team aims to create longer-living cybrids for use in stem cell research. More »

    Scientists ID Leukemia Stem Cells British scientists have identified the stem cells that cause the most common type of childhood leukemia, the Times of London reports. The unprecedented discovery means doctors can monitor cell levels in young cancer patients and stop treatment when those cells are gone, said a leading oncology expert. The work also could help scientists develop therapies targeting the specific cells. More »

    Calif. Firm First to Clone Human Embryos A California lab has cloned a human embryo, a science first; the researchers stopped short, however, of creating stem cells. Using a process called somatic cell nuclear transfer, the scientists fused DNA from a man’s skin cells with donated egg cells—and created an embryo with cells specific to the man. Scientists hope stem cells could replace damaged cells with reduced risk of rejection. More »

    Scientists to Test Promising New Theory on Cancer Cancer researchers are poised to begin what could be a revolutionary approach to treating cancer, the New York Times reports. Instead of trying to destroy tumors, scientists at three leading medical centers will go after cancerous stem cells that feed the tumors. The controversial approach—not all scientists buy the notion of such stem cells—could dramatically change the direction of research and raise hopes for new cures. More »
