Teratoma-forming efficiency of CCTL14 hESCs

Table shows the teratoma-forming efficiency of CCTL14 hESCs grown in colonies with mEFs, early (ML2) and adapted (ML10) monolayer culture, and early (REV p1) and late (REV p5) reverted colonies on mEFs. The cells were treated with Y27632 or left untreated before injection into recipient mice. The numbers in parentheses show the number of mice that developed teratomas compared with the total number of mice that received intramuscular injections of hESCs.

Abbreviations: hESC, human embryonic stem cell; mEF, murine embryonic fibroblast.
