Abstract
Julia Franzen et al. investigate if changes in DNA methylation at specific genetic loci during cell culture expansion are due to a specific mechanism or gradual deregulation of an epigenetic state. Their results suggest that changes in CpG methylation are due to indirect epigenetic drift, rather than a consequence of targeting by DNA methyltransferases.
