Patch Clamp assays, the gold standard of ion channel
research, are distinguished by high complexity. Conventional patch clamp is
technically demanding and is unsuitable for high-throughput screening (HTS)
experiments. Nanion Technologies is one of the
leading providers of automated patch clamp systems, offering a diverse product
portfolio for experiments ranging from single channel recordings to HTS-compatible
ion channel drug discovery. In recent
years, human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have gained increased popularity as they
recapitulate key features of human cardiac ion channel electrophysiology in
vitro. The capacity of a drug candidate to interact with ion channels involved
in the depolarization or repolarization phases of the cardiac action potential
is important for drug safety assessment. Moreover, novel insights into
electrophysiology and contractility in conjunction with optogenetic
stimulation in hiPSC-CMs will be discussed. In the
light of the new Comprehensive in Vitro Proarrhythmia
Assay (CiPA), a FDA directed initiative to improve
guidelines and standardize assays and protocols, the use of hiPSC-CMs
may become critical in determining the proarrhythmic
risk of potential drug candidates. In agreement with the CiPA
initiative, the feasibility of using Nanion’s
automated patch clamping platforms for automated evaluation of the
electrophysiology and pharmacology of hiPSC-CMs will
enable considerable increase in throughput for reliable and efficient drug
evaluation.
