STAP細胞はES細胞よりやや小さいんだね。でもES細胞とSTAP幹細胞は区別がつかない。
STAP細胞が小さいという認識は最初のころは胞子様細胞は小さく存在していて
体細胞内で休眠しているという発想だった。博論草稿にあるよね。

「An assessment of the developmental potential of embryonic stem cells in the midgestation mouse embryo.」
Embryonic stem cells (ES) cells were injected into host blastocysts either in groups of 10-15 cells or as single cells in order to test their developmental potential in the developing embryo. The analysis of midgestation chimaeras, by electrophoretic separation of glucose phosphate isomerase (GPI) isozymes, showed that ES cells were capable of colonizing trophectoderm and primitive endoderm derivatives at a low frequency, as well as producing a high rate of chimaerism in tissues of the fetus and extraembryonic mesoderm.
