Production of virus-free stem cells
Skin cells, the virus re-programmed without the use of a living thing capable of all that, the cells similar to embryonic stem cells were produced.
James Thomson of the University of Wisconsin and the U.S. team has been able to produce these stem cells, heart, lung or nerve cells, such cells could become like the 220. "Human embryos will be your" due to be produced without destroying the cells without causing ethical and religious conflicts that can be used in treatment.
Produced without the use of viruses for the first time this type of cells that are configured Thomson noted that the stem cells to cause tumor activity of certain genes and reduces the risk of stopping too stressed.
Thomson and his team are required to reprogram skin cells to the virus rather than the gene transfer plasmid (a kind of DNA molecule) was used. Research published in the journal Science.
In 1998, embryonic stem cell culture to obtain the first person that Thomson, in 2007, the Japanese counterpart of human skin cells, stem cells turned into a method of improving the patient tissue or organs, changing the revolution can be considered an invention enjoyed.
