Chromatin Usage in Individual Cells Reveals Developmental Trajectories. IMAGE: EMBL (IMAGE) European Molecular Biology Laboratory Caption Both cell type and developmental stage can be deduced from measurements of chromatin accessibility in thousands of single cells, researchers at EMBL and the University of Washington show. They used this approach to uncover how cells in developing embryos regulate their identity as they decide what kind of cell to become. Nature publishes the results on March 14.
