Ensure that the immune rejection does not occur most.

Teams, such as the National Institute of Radiological Sciences, was confirmed by experiments in mice transplanted with bone marrow that even the skin and made ​​from iPS cells (induced pluripotent stem cells), immune rejection does not occur most of the time. The result of expanding the possibilities of clinical application, published in the electronic version of the British science journal Nature dated 10.

realization of regenerative medicine to be implanted into the patient by changing cells and ES cells in various tissues iPS (embryonic stem cells <yes>) has been expected. iPS cells are be made ​​from the patient's own cells, and there is an advantage that rejection does not occur even if the transplanted tissue.

Nature also published the results in 2011, the U.S. team and rejection can occur in transplant using iPS cells, however. I have a question mark to the benefits. Although the need for additional experiments will have a lot, it is a result of expectations of clinical iPS cells is greatly inflated.


放射線医学総合研究所などのチームは、ｉＰＳ細胞（人工多能性幹細胞）から作った皮膚や骨髄を移植しても、免疫拒絶反応がほとんど起きないことをマウスの実験で確かめた。臨床応用の可能性を広げる結果で、１０日付英科学誌ネイチャー電子版で発表する。
　ｉＰＳ細胞やＥＳ細胞（胚〈はい〉性幹細胞）をさまざまな組織に変化させて患者に移植する再生医療の実現が期待されている。ｉＰＳ細胞は、患者自身の細胞から作れば、組織を移植しても拒絶反応が起きない利点があるとされる。
　ところが米国のチームが２０１１年、ｉＰＳ細胞を使った移植で拒絶反応が起きうるとの結果をやはりネイチャーに発表。利点に疑問符がついていた。追実験の必要性は大いにあるでしょうが、iPS細胞の臨床への期待が大きく膨らむ結果ですね。
