Scientists in Switzerland and Pennsylvania sought to understand the role of methylation in stem cell-directed regeneration of the intestinal epithelium in mice. They size selected for 300-600 bp DNA fragments and sequenced them with Illumina. Results indicate that losing DNA methylation at particular enhancer sites delayed stem cell differentiation and led to unusual gene expression, both of which could contribute to development of cancer.
