Action potential characterization of human induced pluripotent stem cell-derived cardiomyocytes using automated patch-clamp technology.
Recent progress in embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC) research led to high-purity preparations of human cardiomyocytes (CMs) differentiated from these two sources-suitable for tissue regeneration, in vitro models of disease, and cardiac safety pharmacology screening. We performed a detailed characterization of the effects of nifedipine, cisapride, and tetrodotoxi...
متن کاملAutomated patch clamp on mESC-derived cardiomyocytes for cardiotoxicity prediction.
Cardiovascular side effects are critical in drug development and have frequently led to late-stage project terminations or even drug withdrawal from the market. Physiologically relevant and predictive assays for cardiotoxicity are hence strongly demanded by the pharmaceutical industry. To identify a potential impact of test compounds on ventricular repolarization, typically a variety of ion cha...
متن کاملAutomated planar patch-clamp.
Ion channels are integral membrane proteins that regulate the flow of ions across the plasma membrane and the membranes of intracellular organelles of both excitable and non-excitable cells. Ion channels are vital to a wide variety of biological processes and are prominent components of the nervous system and cardiovascular system, as well as controlling many metabolic functions. Furthermore, i...
متن کاملPatch-Clamp Recording from Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes: Improving Action Potential Characteristics through Dynamic Clamp
Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) hold great promise for studying inherited cardiac arrhythmias and developing drug therapies to treat such arrhythmias. Unfortunately, until now, action potential (AP) measurements in hiPSC-CMs have been hampered by the virtual absence of the inward rectifier potassium current (IK1) in hiPSC-CMs, resulting in spontaneous acti...
متن کاملAutomated voltage-clamp technique.
The voltage-clamp electrophysiology method is the gold standard for measuring the function of ion channels. In the past, this technique has had limited applicability in pharmaceutical drug discovery because of its low throughput, steep learning curve, and challenges in standardization of the experiments. Recently, new electrophysiology platforms have been developed, which are based on the use o...
