High prevalence of acquired cancer-related mutations in 146 human pluripotent stem cell lines and their differentiated derivatives.

Abstract excerpt

To survey cancer-related mutations in human pluripotent stem cells and their derivatives, we analyzed >2,200 transcriptomes from 146 independent lines in the NCBI's Sequence Read Archive. Twenty-two per cent of samples had at least one cancer-related mutation; of these, 64% had TP53 mutations, which conferred a pronounced selective advantage, perturbed target gene expression and altered cellular differentiation....
