Human Embryos Just Survived 13 Days in a Petri Dish

Opens the door to study what happens in the mysterious, critical first days of life

(Newser) - It's a milestone that's at once being called groundbreaking and a Pandora's box: Scientists at Cambridge University surprised even themselves by growing embryos for 13 days outside the womb—one day short of a longstanding legal limit that's never been pushed up against because embryos failed...

Nobel Prize for Medicine Goes to Stem Cell Scientists

John Gurdon, Shinya Yamanaka share the prize

(Newser) - The first of this year's Nobel prizes was announced this morning, with a British scientist and a Japanese scientist sharing the prize for medicine. John Gurdon and Shinya Yamanaka helped discover that specific and mature cells "can be reprogrammed to become immature cells capable of developing into all... More »

Scientists Breed Mice From Stem Cell Alternative

Researchers turn adult, not embryonic, skin cells into stem cells

(Newser) - Scientists in China have created mice using stem cells made from modified skin cells—hinting at an alternative to embryonic stem cells, the Washington Post reports. Separate teams used viruses to manipulate genes that caused mice skin cells to regress back into induced pluripotent stem cells—which, within a placenta... More »

Gore, Righties Bond Over Non-Embryonic Stem Cells

(Newser) - Some conservatives see recent investments by Al Gore’s venture-capital group into stem-cell research involving a non-embryonic variety as a tacit denial of that more invasive method, the New Scientist reports. Gore’s company has put $20 million into a project researching treatment with induced pluripotent stem cells, which do... More »

New Research Raises Hopes for Viable Human Cloning

Study finds cloned embryos share genetic traits with natural cells

(Newser) - Human cloning, for medicine or even reproduction, may be more realistic than ever, Wired reports. Researchers found genetic characteristics similar to normal human embryos in cloned human embryos. The findings are a first step toward therapeutic cloning, in which embryonic stem cells that can replace failing tissues are grown from... More »

Docs Tout Safer, Non-Embryonic Stem Cells

Virus, used in mice, repurposes adult cells with no risk of cancer

(Newser) - Scientists have discovered a safer way to turn adult cells into stem cells, the Boston Globe reports. The cells, similar to those harvested from embryos, are called induced pluripotent stem, or iPS, cells; Japanese researchers introduced the method 2 years ago. But the Japanese used retroviruses, which can cause cancer;... More »

Scientists Reprogram Adult Cells

Breakthrough could leap embryonic stem-cell quagmire

(Newser) - In a stunning medical advance, scientists have found a way to transform an adult cell in a living animal into an entirely different type of cell. The development is another step toward freeing the field of regenerative medicine from the controversies of stem-cell research. Harvard biologists discovered three key molecular... More »

Scientists See Breakthrough in Stem Cell Production

Research holds promise for Lou Gehrig's disease

(Newser) - A US team has made a breakthrough in stem cell research, growing new nerve cells from the skin of patients suffering from Lou Gehrig's disease, or ALS. The work marks the first time disease-specific stem cells have been generated from a patient.The method could be used to tailor replacement... More »
