# brain: somatic stem cell proliferation could be modulated by autonomic nervous system

this << study (..) demonstrates, for the first time, that stem cell proliferation is directly controlled by the autonomic nervous system (ANS). >>

<< To demonstrate that stem cell behavior was changing as a result of ANS stimulation, the researchers grew intestinal epithelial cells in the lab and exposed them to high levels of two neurotransmitters, norepinephrine and acetylcholine. Norepinephrine is a major neurotransmitter of the sympathetic nervous system, or "fight or flight" branch of the ANS, while acetylcholine is produced by the parasympathetic nervous system, or "rest and digest" branch. >>
