cells from human skin cells fabricated universal success

Kyoto University and the American University of Wisconsin two research groups almost simultaneously, skin cells from human embryonic stem cells (embryonic stem cell: embryonic stem cells) very closely versatile cells that produce success.

ES cells of the body with the ability to become any cell pluripotent cells in the treatment of various diseases potential use is expected to gather.However, stem cells taken to the subsequent growth that can destroy the embryo must be the ethical aspects of the discussion by calling. The second study showed how embryos are not used for such a discussion to avoid it.

University of Wisconsin researchers who led James Thomson, "said stem cells essentially the same thing from a mature cell is shown how to produce it in the ethical discussion has been a change brought about," he said .Meanwhile, Japan's Kyoto University who led the study of the mountains of Wataru Shin professor, "This cell is the understanding of the disease mechanism and the effective and safe drug development, such as cell therapy could help," he said.However, treatment can be applied until the road is distant and the Texas A & M University Health Science Center, said Robert Tsai said.the mountains, they will study medical journal "Cell" on November 30 issue of the University of Wisconsin study of "Science" online edition on Nov. 20 appeared.

　 Both teams using fundamental principle is almost the same in the mountain's team, the retrovirus (cancerous cells associated virus) using skin cells to the four genes embedded. University of Wisconsin team in the mountains, they are using gene is two different things. Fabricated "iPS cells (induced pluripotent stem cell: induction pluripotent stem cells)" is the appearance of cell culture and nature in terms of the ES cells ME very similar to that of the 30,000 pieces of genetic strength of the results examined the approximately 1,000 gene expression is different in that it is OK.

IPS this human cells, ES cells to replace and determine whether the need to further study after another.
Thomso. IPS cells by the emergence of stem cell research is not the end, the future of stem cell research is used as it is supposed to be scarce and Thomson said.

Yamanaka said, fabricated using a retrovirus because iPS cells with carcinogenic possibility that the safety check can also challenges for the future. Also, iPS cells from the sperm and egg cells produced by the cell in iPS ethical problems arise.To avoid misuse, iPS human cells manufacture and use of the appropriate regulations to implement it as vital to the mountains, he said.
