Pluripotent cells of the early embryo, to which embryonic stem cells (ESCs) correspond, give rise to all the somatic cells of the developing fetus. Any defects that occur in their genome or epigenome would have devastating consequences. Genetic and epigenetic change in human ESCs appear to be an inevitable consequence of long-term culture, driven by(More)
Human embryonic stem cells (hESCs) tend to lose genomic integrity during long periods of culture in vitro and to acquire a cancer-like phenotype. In this study, we aim at understanding the contribution of point mutations to the adaptation process and at providing a mechanistic explanation for their accumulation. We observed that, due to the absence of(More)
