Organ grown with patient's stem cells

Nov 19, 08 4:49 AM CST
(Newser) - In a frontier-busting surgery, transplant doctors have given a young woman a trachea developed in a lab using the patient's own stem cells. Stem cells from the patient's trachea and bone marrow were used to create a new rejection-proof organ in the surgery, performed in Spain in June, reports the... More »

Study finds mice's own stem cells most effective vs disease

Mar 24, 08 9:00 AM CDT
(Newser) - Scientists have found that embryonic stem cells effectively treat Parkinson's disease in lab mice, but only when the cells come from the sick mouse's own clones, Reuters reports. The study, published in Nature Medicine, created "therapeutic clones" by transferring cell nuclei into mouse egg cells and growing them into... More »

Discovery holds promise for treatment
of childhood cancer

Jan 18, 08 7:09 AM CST
(Newser) - 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... More »

Calif. Firm First to Clone Human Embryos

Move could aid development of new stem-cell lines

Jan 17, 08 4:38 PM CST
(Newser) - 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... More »

Scientists Rebuild Heart With Stem Cells

Advance could save heart disease patients, regrow other organs

Jan 13, 08 7:04 PM CST
(Newser) - Scientists rebuilt rat and pig hearts using stem cells taken from the recipients themselves, the Telegraph reports—a medical breakthrough that could help the 22 million people who suffer from heart failure worldwide. The technique, called whole organ decellularization, produced the world’s first functioning “bioartificial” heart within eight... More »

Stem Cells Made Without Destroying Embryos

Blastomere biopsy may finally overcome ethical obstacles

Jan 10, 08 5:43 PM CST
(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,... More »

Third Team Turns Skin
Into Stem Cells

First time cells were taken from a volunteer, not lab grown

Dec 24, 07 4:40 AM CST
(Newser) - A third team of scientists has successfully turn skin cells into stem cells that can be coaxed into becoming any kind of tissue. The American researchers are the first group to manage the feat with a volunteer's cells, not cells grown in a lab, which demonstrates that such cells could... More »

Scientists to Test Promising New Theory on Cancer

Medical centers will directly attack cancerous stem cells

Dec 21, 07 4:00 AM CST
(Newser) - 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...

Skin Stem Cells Cure
Sickle Cell in Mice

Latest advance in revolutionary research

Dec 7, 07 3:28 AM CST
(Newser) - In the latest advance in revolutionary new stem cell research, scientists have cured sickle-cell anemia in mice using stem cells made from skin. It's the first proof that such cells can be used to cure hereditary diseases. But because the cure involved the use of viruses to alter DNA, significant... More »
