Two Signals -- From Within And Out Of Cell -- Specify Motor Neuron Differentiation

ScienceDaily (June 10, 2009) — Two signals – an external one from retinoic acid and an internal one from the transcription factor Neurogenin2 – cooperate to activate chromatin (the basic material of chromosomes) and help determine that certain nerve progenitor cells become motor neurons, said researchers from Baylor College of Medicine in a report in the current issue of the journal Neuron.
