I established STAP-SC several times from STAP. It is unlikely that contamination would always have happened. In addition, we established STAP-SC from 129B6GFP mice. At that time, we did not have this strain ES cell.
When I succeeded to establish STAP-SC, the original STAP cells expressed Oct4-GFP very much. In this condition, the establishment is much easier than ES cell establishment from blastocyst.
In addition, whole mRNA expression data suggest that STAP-SC are not ES cell.
