そう、我々も何度も確認しているところだ。さて、そこで本論さ。
The latter sentence seems to be an additional, if simple, “mistake,” Wakayama said via email. He made stem cells from the STAP cells she said came from 129 mice. But he never made chimeras from the 129 cells, as stated in the paper (and Niwa protocol). “I gave 129 mice to Dr. Obokata. Then, Dr. Obokata generated STAP cells from those mice, and gave me two STAP cells. I do not know how many STAP cells were generated at that time. I got just two. Then, I established two STAP stem cell lines from those two STAP cells. However, I did not make chimera from those cell lines. Then I left RIken." In another email he clarified: "I left Riken one year ago. Then we could not (establish) contact well between authors. Maybe Dr. Sasai, who wrote the papers, thought that I did chimera experiment of 129.”
