The authors surveyed whole-exome and RNA-sequencing data from 252 unique pluripotent stem cell lines, some of which are in the pipeline for clinical use, and found that approximately 5% of cell lines had acquired mutations in the TP53 gene that allow mutant cells to rapidly outcompete non-mutant cells, but do not prevent differentiation.
