Objective: For human embryonic stem cells (hESCs) to differentiate into neurons, enormous changes has to occur leading to trigger action potential and neurotransmitter release. We attempt to determine the changes in expression of voltage gated channels (VGCs) and their electrophysiological properties during neural differentiation. Materials and methods: The relative expressions of alpha-subunit of voltage gated potassium, sodium and calcium channels were characterized by qRT-PCR technique. Patch clamp recording was performed to characterize the electrophysiological properties of hESCs during their differentiation into neuron-like cells. Results: Relative expression of a -subunit of channels changed significantly. 4-AP and TEA sensitive outward currents were observed in all stages, although TEA sensitive currents were recorded once in rosette structure. Nifedipine and QX314 sensitive inward currents were recorded only in neuron-like cells. Conclusion: K+ currents were recorded in hESCs and rosette structure cells. Inward currents, sensitive to Nifedipine and QX314, were recorded in neuron-like cells. (C) 2017 Elsevier Inc. All rights reserved.
