Figure. Timelapse movie of sarcomeres in beating cells. Time-lapse movie of live hiPSC-derived cardiomyocytes expressing mEGFP-tagged troponin I. Cells were continuously imaged on a spinning-disk confocal microscope with a 100ms exposure time. Inset shows detail of sarcomeres in myofibrils. Scale bars, 5 µm and 10 µm for inset and larger field respectively. Movie plays in real time.
