Cell atlases chart the molecular information of cells including its genetic make-up and the molecular changes along the cell’s lifespan. This information deepens our understanding of cell-to-tissue and disease development. In a Science Perspective article, Barbara Treutlein and colleagues at Roche’s Institute of Human Biology now question “What is a cell type?”, and call for future research into charting perturbations which alternate the cell’s molecular phenotype.

Variations in the cellular DNA occur frequently and are passed on to descending cells, thereby tracking the evolutionary history of cell populations. In a study published in Cell Genomics, researchers from the Computational Biology group of Niko Beerenwinkel utilized DNA variations to investigate the evolutionary rates in single cells from healthy and cancer tissues. They found that most cancer cells vary in their evolution rate, and also many healthy tissues show evidence for varying rates.
