High Prevalence of Acquired Cancer-related Mutations in 146 Human Pluripotent Stem Cell Lines and Their Differentiated Derivatives
Overview
Affiliations
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. These findings underscore the need for robust surveillance of cancer-related mutations in pluripotent cells, especially in clinical applications.
