Electrical phenotype of a cryopreserved AFSC suggestive of neuronal differentiation. a Absence of outward rectifying currents. b Large voltage-dependent Na⁺ currents. c Large inward rectifying K⁺ currents elicited by hyperpolarizing steps from −60 to −120 mV from a holding potential of −60 mV. d I–V plot of the inward rectifying current shown in c and its partial inhibition by RuR 100 μM
