Human Induced Pluripotent Stem Cell Derived Cardiomyocyte Electrophysiology and Experimental Reproducibility
Manage episode 431301908 series 3479554
Sometimes experimental results are serendipitous. Listen as Associate Editor Dr. Crystal Ripplinger (University of California, Davis) talks with authors Dr. Nikki Posnack and Devon Guerrelli (both at Children’s National Hospital and The George Washington University School of Engineering and Applied Science), along with expert Dr. Silvia Marchiano (University of Washington), about the new research by Guerrelli et al. published in our Call for Papers on Excitation-Contraction Coupling, Electrophysiology, and Arrhythmias. The Posnack Lab typically investigates environmental chemicals and their impact on cardiac function using microelectrode arrays to record electrical signals from human iPS cells. When performing cardiotoxicity experiments, the authors realized that their baseline measurements varied significantly between their different studies, making it difficult to combine datasets. In doing the legwork to identify potential sources of variability and improve their own internal lab protocols, the authors focused on the reproducibility of their experimental measurements using human iPSCs. Listen as we discuss important recommendations for investigators using these cells to improve their experimental reproducibility.
