The presence of STAP cells it would be virtually negated.

A problem over the STAP cell paper, verification experiments Cobo how the author Haruko-RIKEN researchers confirm the presence or absence of the STAP cells was working until the end of November, that it was not possible to create a cell in the same manner as paper, officials I was revealed in an interview to. RIKEN the 19th morning, to announce the results of experiments RIKEN of verification team that does not matter whether the Cobo how Mr. and Cobo how Mr.. Increased likelihood of experiments will abort the verification team, so that the presence of STAP cells are effectively negated.
RIKEN established a verification team that Vice President later in April, RIKEN Center for Developmental Biology of Shinichi Aizawa Special Advisor (at the time). Over up to one year, in terms of mouse cells is confirmed to be acquired versatility by stimulation such as immersion in a weakly acidic solution, the cells were put into a fertilized egg is allowed to differentiate into whole body cell "chimeric mouse" the was trying to make.
Cobo how Mr. participate in the verification experiment from July. Under the third-party presence, and worked to reproduce the experiments described in the paper. However, according to the officials, in and gene of mark of versatility to work experiments with mouse lymphocytes genetically engineered to shiny green, cell glowing in green and be given the stimulus could be slightly confirmation just, as often as the paper did not appear. In addition, that also did not succeed in chimeric mice produced.
Cobo how Mr. has been described as "more than 200 times successful" in the production of STAP cell at a press conference that opened in April.
In verification team interim report of August, in the method described in the paper announced that it had failed STAP cells. It was scheduled to continue until next March while changing team of experiment conditions, according to the officials, "more than Cobo how Mr. could not be reproduced, meaning thin to continue" as is likely to be aborted.
I'll Although STAP cells were surprised to Dekiagaru no choice but to deny the existence of the cell itself when it comes and not guaranteed is important reproducibility in science too easy way.


ＳＴＡＰ細胞論文を巡る問題で、著者の小保方晴子・理化学研究所研究員が１１月末まで取り組んでいたＳＴＡＰ細胞の有無を確かめる検証実験で、論文と同じ手法で細胞を作製できなかったことが、関係者への取材で明らかになった。理研は１９日午前、小保方氏と小保方氏か関わらない理研の検証チームの実験結果について発表する。検証チームの実験も打ち切りになる公算が大きく、ＳＴＡＰ細胞の存在が事実上否定されることになる。
　理研は４月以降、理研発生・再生科学総合研究センターの相沢慎一特別顧問（当時）を統括責任者とする検証チームを設置。最長１年かけて、マウスの細胞が弱酸性の溶液に浸すなどの刺激によって万能性を獲得することを確認したうえで、この細胞を受精卵に入れて全身の細胞に分化させる「キメラマウス」を作ることを試みていた。
　小保方氏は７月から検証実験に参加。第三者の立ち会いの下で、論文で記載した実験の再現に取り組んだ。しかし、関係者によると、万能性の目印となる遺伝子が働くと緑色に光るように遺伝子操作したマウスのリンパ球を使った実験で、刺激を与えても緑色に光る細胞はわずかに確認できただけで、論文のように頻繁には出現しなかった。また、キメラマウス作製にも成功しなかったという。
　小保方氏は４月に開いた記者会見でＳＴＡＰ細胞の作製に「２００回以上成功した」と説明していた。
　検証チームは８月の中間報告で、論文に記載された方法ではＳＴＡＰ細胞ができなかったと発表した。チームの実験は条件を変えながら来年３月末まで続ける予定だったが、関係者によると「小保方氏が再現できなかった以上、継続する意味は薄い」として、打ち切られる可能性が高い。
　あまりにも簡単な方法でSTAP細胞が出来上がるのにビックリしたが科学で重要な再現性が保証されないとなると細胞自体の存在を否定せざるをえないでしょうね。
