Polycomb enables lineage priming in mouse embryonic stem cells by establishing a barrier to commitment.

The probability of a cellular response to a differentiation inducing signal is correlated with the dynamic expression of a Ras protein, and produces a ‘salt and pepper’ pattern of cell differentiation.

The ZF-CxxC protein FBXL19 recruits kinase-associated Mediator to CpG islands of silent developmental genes in embryonic stem cells, which primes these genes for activation during differentiation and is required for embryonic development.

Investigation of meiosis in the nematode Pristionchus pacificus has illuminated evolutionary variation in this essential aspect of reproduction and established a new model for future study.

The simultaneous expansion of G1 and acceleration of the cell cycle, while ensuring synchronous inheritance of these properties, progressively induces cell identity in differentiation.

Spatial and temporal cues intersect, likely via enhancer-promoter looping, to turn on a master identity switch that in turn dictates natural lineage reprogramming with high efficiency and temporospatial precision.

Introgression makes hemiplasy more likely, and the probability of hemiplasy incorporating incomplete lineage sorting (ILS) and introgression can be estimated using the presented simulation software.

Terminal selectors reorganize postmitotic neuronal chromatin to select cis-regulatory elements during 5-HT neuron maturation.

Single-cell transcriptome analysis of sacral compared with vagal neural crest-derived cells in the developing chick enteric nervous system reveals both similarities and differences between these two cell populations.

The chestnut blight fungus has successfully established an intermediary, diverse European bridgehead population, giving rise to a highly invasive clonal lineage spreading across southeastern Europe.
