Transcription factors that specify the identity of individual neuron types via activating terminal differentiation gene batteries also restrict cellular plasticity via altering the chromatin landscape.

5-Hydroxymethylcytosine-mediated active DNA demethylation occurs in postmitotic neurons, and is required for their terminal differentiation and function.
JNK pathway activity induces spermatogonial dedifferentiation under challenging conditions to maintain the germline stem cell pool and to endow it with potentially fitter cells that have increased proliferation.

Single cell RNA sequencing reveals that mouse embryonic stem cells can be differentiated into the same terminal motor neuron state via distinct differentiation paths, one of which includes a surprising intermediate state not found in embryos.
Proteasome-mediated degradation of the TATA-box binding protein (TBP) during terminal differentiation is regulated by the E3 ligase Huwe1 and the deubiquitinase USP10.
Inhibiting PRMT1 enzymatic activity promotes megakaryocyte terminal differentiation via RBM15-mediated RNA metabolism, which is dysregulated in hematological malignancies.
Irreversible differentiation into somatic cells is evolutionarily optimal if changing cell phenotype is costly, a few somatic cells already improve the organism's performance, and the organism is large enough.

The juxtacrine signaling molecule EphA7, when expressed on terminally-differentiated myocytes, non-cell-autonomously induces adjacent myoblasts to also commit to terminal differentiation leading to rapid coordinated differentiation across the entire population.
