New Technique Stem Cell Can Growth Cancer Tumors

A newly medical technology discovered techniques to produce stem cells that is a breakthrough indeed did produce stem cells that can cause cancer in organisms that grow from them.

Two different teams of scientists menmberikan announcements about new techniques to develop stem cells in the same month. In an article published online edition of the journal Cell, Dr. Shinya Yamanaka and his colleagues argue that they have transformed human skin cells into stem cells using a virus by injecting skin cells with four specific genes.

Yamanaka and colleagues at Kyoto University, Japan used to using mouse skin cells into stem cells via the same technique. Yamanaka and his colleagues are now setting up a laboratory at the Gladstone Institute of Cardiovascular Disease, which is associated with the University of California at San Francisco.

At about the same time, a team of researchers from the University of Wisconsin at Madison announced in the online edition of the journal Science that they have transformed human skin cells into stem cells via the same technique, but using four different genes.

Stem cells are cells that retain the ability to transform into another cell type. This ability makes them focus on one of the many studies in the hope they will be able to use it to grow tissue for victims of severe injury or degenerative disease. Because many stem cells derived from human embryos were destroyed. However, many stem cell research gained a lot of controversy from anti-abortion activists, and women's rights advocates who objected because the invasive procedure required to harvest the eggs to keep them alive for the next process.

While still experiencing controversial, stem cells generated by the new technique appears to be carcinogenic. When the team into the cell mouse embryos implant Yamanaka, their embryos developed as expected - with DNA from the original stem cells, rather than from embryos. But mice that were cloned with this model eventually experienced neck tumors.

"It seems everyone in the mainstream media are very excited to know about the new stem cell technique that they forget to realize the fact that it led to the growth of cancerous tumors," said consumer health advocate Mike Adams.
