Is action potential an electrical signal
WebASCs exhibit slow, spontaneous Ca 2+ oscillations and the manipulation of Ca 2+ signalling via electrical stimulation was proposed as a potential route for promoting their differentiation in vivo. However, the effects of differentiation-inducing treatments on spontaneous Ca 2+ oscillations in ASCs are not yet fully characterised.
