Question deepens in reverse.

Experimental results 19 days, virtually deny the existence of STAP cells, was announced. In Haruko Obokata researcher and RIKEN of validation experiment team experiment was working respectively, STAP cells with the "versatility" that changes in various tissues can not be produced, the cells that have been shown in a paper called What was question was deepened to reverse. RIKEN advances the understanding of the identity of the cells with the STAP in the survey committee of outside experts, plans to publish until early February next year.
According to the RIKEN, Cobo how Mr. experiments were carried out in the room with a surveillance camera a third party witness. In technique to attach the cells to the acidic liquid indicated in the paper, although in some cells was observed emission phenomenon is a measure of versatility, special uses a mass of about 1600 cells of luminescence was confirmed make a such mice, experiments to confirm the versatility of the cells did not succeed. Although similar emission was also observed in the verification team experiments, could not be special mouse.
The STAP cells there is negative, there it is pointed out that whether the research is not to was the "embryonic stem cells (ES cells)" universal cell that precedes, the investigation committee RIKEN was established in September, Cobo how use the data, such as the sample which has been frozen in his laboratory, is being investigated. By all means, and I want to elucidate the What was. I wish was good if Anyway remain detailed study notes. I because it does not guarantee conditions also reproducibility and is not clear.



ＳＴＡＰ細胞の存在を事実上否定する実験結果が１９日、発表された。小保方晴子研究員と理化学研究所の検証実験チームがそれぞれ取り組んでいた実験で、さまざまな組織に変化する「万能性」を持つＳＴＡＰ細胞は作製できず、論文に示された細胞は何だったのかという疑問は逆に深まった。理研は外部有識者による調査委員会でＳＴＡＰとされた細胞の正体の解明を進め、来年２月上旬までに公表する方針だ。
　理研によると、小保方氏の実験は第三者が立ち会う監視カメラ付きの部屋で行われた。論文に示された酸性の液に細胞を漬ける手法でも、一部の細胞では万能性の目安となる発光現象が見られたが、発光が確認された約１６００個の細胞の塊を使って特殊なマウスを作り、細胞の万能性を確認する実験は成功しなかった。検証チームの実験でも同様の発光が認められたが、特殊なマウスはできなかった。
　存在が否定されたＳＴＡＰ細胞とは、研究が先行する万能細胞の「胚性幹細胞（ＥＳ細胞）」だったのではないかとの指摘があり、９月に理研が設置した調査委員会が、小保方氏の研究室内で冷凍保存されていた試料などのデータを使い、調査している。ぜひ、何だったのかを解明して欲しいですね。それにしても詳細な研究ノートが残っていれば良かったのにね。条件が明確でないと再現性も保証されないですからね。
