STAP cells contributed not only to the embryo but also to the placenta and fetalmembranes (Fig. 1b and Extended Data Fig. 1a–c) in 60% of the chimaeric embryos (Fig. 1c).と
書いたのは笹井さんよ。not only to the embryo but also to the placenta and fetalmembranesと小保方さんの原稿にあったとしてもand fetal membranes と続いたときに気づくでしょ。
彼は気づかなかったのよ。なぜ？
>These results support the view that the RNA-seq data contained transcripts from two major cell populations, with approximately 90% B6 cells having an ESC-like expression pattern and approximately 10% CD1-like cells having a TSC-like pattern. Therefore, the claim in the Obokata et al. paper that FI-SCs contribute to the placenta might have been based in error on contamination by TSCs, which are known to be organ stem cells (Tanaka et al. 1998).

The authors claim that "Surprisingly, injected STAP cells contributed not only to the embryo but also to the placenta and fetal membranes (Fig. 1b and Extended Data Fig. 1a??"c) in 60% of the chimaeric embryos (Fig. 1c)." and they show the analysis of chimaeric embryos with placentas at E12.5. I'm sorry to say but that is normal in E12.5 chimaeric embryos produced by injection of wt ES cells into blastocyst, since the placental FETAL blood vessels and yolk sac mesoderm cells are derived from the ES-cell derived epiblast.
