In a landmark paper, researchers at Stanford University have described a new way to derive human induced pluripotent stem cells (iPSCs) without the use of contaminating mouse feeder cells. Using adipose cells as the starting cell population and mTeSR1, a defined medium that allows the expansion of human embryonic and induced pluripotent stem cells without the use of feeders, the researchers were able to fully reprogram the cells to the pluripotent state.
mTeSR1 is a fully defined medium and is the most widely used feeder-independent method for culturing human pluripotent stem cells, with citations in more than 25 publications.

“What I cannot stand, what really gets me, is that we have set up a scam, in which Italy says that for moral reasons it is against embryonic stem cell research, but then it reaps the benefits from the research: if Italy is truly against stem cell research, the government must say that Italian citizens will never benefit from the discoveries that will come from the research”, said Italian researcher Elena Cattaneo, who spoke at the 2nd World Congress for “freedom of research’ of the Luca Conscioni Association in Brussels.

One factor, not four like a majority of biologists throughout the world have said up until now, is sufficient to convert an adult stem cell into a cell that is similar to an embryonic stem cell. A recipe that is much more simple than what the scientific community has believed has been discovered by Hans Schöler and his colleagues, who include Italians ,Vittorio Sebastiano and Luca Gentile, from the Max Planck Institute for Molecular Biomedicine in Germany. The study, published in February’s edition of Cell, shows for the first time that nerve stem cells taken from

After making news on several occasions, scientists may have made a definitive breakthrough, with the first possible transfusion using blood obtained from embryonic stem cells possibly coming within the next three years. The transfusion would be done with type O blood, which can be donated to any patient, and would be obtained by researchers using excess embryos from assisted fertilization. The project, which will be led by Marc Turner of Edinburgh University, will also receive contributions from the Transfusion and Transplant Service of the British National Health Service, as well as the
In his latest defiance of the federal government, Gov. Rick Perry is trying to make Texas the nation’s top provider of an unlicensed therapy touted by some as the future of medicine but considered not close to ready for mainstream use by scientists in the field.
Perry this summer worked with his Houston doctor and a state legislator with multiple sclerosis to write legislation intended to commercialize the controversial therapy, which involves injecting patients with their own stem cells. Perry quietly got the therapy as part of back surgery in July.
“With the right policies in place, we can lead the
