Geron abandons stem cell research

Geron abandons stem cell research

A company that pioneered embryonic stem cell research is walking out on the field it helped to create. Geron, based in Menlo Park, California, announced yesterday that it would kill off its stem cell program — and its landmark clinical trial of a treatment for spinal cord injuries — so that it can focus on cancer therapies.  Read more

Mississippi votes against embryos’ human rights, but national debate continues

Mississippi votes against embryos’ human rights, but national debate continues

Yesterday, Mississippi voters headed to the polls to weigh in on a highly controversial ballot initiative that would give embryos in that state ‘personhood’ status, and wreak havoc on reproductive therapy and research in the process. Despite the fact that the constitutional amendment, known as Initiative 26, was supported by Republican and Democrat candidates for Mississippi Governor as well as the state’s Attorney General Jim Hood, it ultimately failed as 58% of the voters rejected it.  Read more

First stem cells created from cloned human embryos — but they’re triploid

First stem cells created from cloned human embryos — but they’re triploid

Researchers in New York have succeeded where the disgraced South Korean Hwang Woo-suk failed. They have successfully derived the world’s first stem cells from a cloned human embryo. But, notably, the new stem cells are not suitable for therapeutic use because they contain three sets of chromosomes, instead of the regular two.  Read more

First embryonic stem cell trial approved outside the US

An embryonic field seems to be developing rapidly. Just two months after Advanced Cell Technology (ACT) launched the second and third trials involving human embryonic stem cell (ESC) derived products in an operating room at the University of California–Los Angeles, the Santa Monica-based biotech announced today that it had gained approval from the UK Medicines and Healthcare products Regulatory Agency to conduct the first ESC cell trial outside the US.  Read more

NEWS FEATURE: Taking tissue engineering to heart — a look at the first US trial of tissue-engineered blood vessels

More than a decade after Japanese scientists implanted the first bioengineered blood vessel into a child with a congenital heart defect, the experimental treatment has finally made its way into clinical testing in the US. Elie Dolgin asks what took so long and what lessons have been learned along the way.  Read more

Mutations in mitochondrial DNA provide another strike against induced stem cells

In 2007, after the University of Wisconsin’s James Thomson first created induced pluripotent stem (iPS) cells from human skin tissue, he told the New York Times that “by any means we test them they are the same as embryonic stem cells.” But over the past year or so, researchers have begun to realize that isn’t the case.  Read more

US judge rules decisively for federal funding of human embryonic stem cell research

US judge rules decisively for federal funding of human embryonic stem cell research

In a victory for supporters of human embryonic stem cell (hESC) research, a US district judge ruled today that government funding of the research is legal, despite an existing law that prohibits US funding of research in which an embryo is destroyed.  Read more

The running of the stem cells: Shinya Yamanaka wins Spain’s top biomedical honor

The running of the stem cells: Shinya Yamanaka wins Spain’s top biomedical honor

MADRID — Adding another notch to his belt of international accolades, stem cell pioneer Shinya Yamanaka of Kyoto University was named the third annual winner of the BBVA Foundation Frontiers of Knowledge Award in Biomedicine. At the award ceremony, held here last month at the Palace of the Marqués de Salamanca, a who’s who of Spanish and international scientific and political elite drank sangria and ate tapas to toast the winners in the eight different categories celebrated by the foundation.  Read more
