Summary

The intracellular potential in gallbladder epithelial cells is about −59 mV with respect to both mucosal and serosal media.

It is a diffusion potential mainly due to K+; Na+ conductance seems to be very low. Entrance of Cl− into cells appears to be coupled with Na+ on a neutral carrier and exit towards blood side seems to be due to a NaCl neutral pump.
