6月4日《The Japan Times》报道，日本理化学研究所（Riken）研究人员Takaho Endo利用遗传数据表明表明小保方晴子培养的细胞有可能是混合了两种不同类型的细胞（Endo’s analysis of the genetic data found that the stem cells cultivated possessed mixed features of embryonic stem cells and trophoblast stem cells. The latter are capable of developing into a placenta, while the former are known to lack the ability to develop into certain parts of a placenta. Also, the type of mice created in the experiment were “B6″ and “CD1,” not “F1″ as claimed by the researchers, Endo said.），并指出“这不可能是偶然或错误所致，两种类型的细胞是有意混和的。（“It is quite unlikely that this happens as a result of an accident or mistake,” Endo said, adding that the two kinds of cells could have been mixed intentionally.）”

    在第一篇论文被同意撤掉后，小保方晴子近日也在同意撤回第二篇论文（有关STAP细胞的Article，有关STAP细胞的制作方法及其万能性的研究成果。）的文件上签字。据称，小保方于6月3日向论文合着者之一的理研的丹羽仁史项目负责人提交了这一文件。理研方面认为这意味着“已经以书面形式同意撤回”。（On Tuesday, however, Obakata signed a document agreeing to the paper’s retraction and submitted it to her co-authors, Riken said. She had already agreed to withdraw the secondary paper.）《The Japan Times》报道《Besieged Obokata agrees to retract primary STAP cells paper》说：“日本理化学研究所（Riken）无意再深入调查此事（Riken does not intend to investigate the matter further.）”

    《The Asahi Shimbun》的一篇报道《Obokata, Vacanti heed request by Nature's editors to retract article》：小保方晴子向她的律师Miki 说她之所以感到没有选择只能同意撤回论文，是因为她想被理研所邀请参与再审查过程（“Miki said Obokata told him that she felt she had no choice but to agree to withdraw the article because she wants to be invited to participate in Riken’s re-examination process.”）

    《The Japan Daily Press》的一篇报道《Japanese stem cell scientist Obokata finally agrees to retract papers on STAP cells》说她同意撤回两篇论文并不等于承认对她研究造假的指控（Her agreement to retract both papers is not tantamount to admitting the allegations of fabrication and manipulation in her research.）

    想想，小保方晴子虽然论文出版后就受到质疑，但她信誓旦旦地说她曾制作STAP细胞“至今为止成功了200多次。”早前理化所调查时她仍坚称如果结果是可靠的（Japan stem cell researcher says results valid），如果让她返回实验室她可以重复出来（The phenomenon of ordinary cells transforming into stem cells under the influence of external stimulus was “confirmed many times for a fact,” Obokata said at the press conference in the western city of Osaka. She said she could replicate her results again if allowed back into the lab to do so.）

    美女科学家小保方晴子的事完了没完？她是在嘴硬，还是真有可能翻盘？
