Darren Cusanovich, PhD, led a study published in the most recent issue of Cell presenting a single-cell atlas of chromatin (how the genome is packaged in the nucleus of a cell) patterns in adult mice based on data from almost 100,000 individual cells. Their work sheds light on how the various cell types present in mammals are able to accomplish such different functions while referencing the same genome. This resource may ultimately help us to understand precisely how human diseases develop and manifest in complex tissues. PMID: 30078704
