Bioelectricity and embryonic patterning
All cell membranes present an electric potential. This is called the Resting Membrane Potential (RMP) and is the trace of the difference of ionic charges between the extracellular and the intracellular spaces. This is very well known in the so-called excitable cells (e.g. neurons, muscles) which can change their electric potential thanks to ion channels…
