Electrical Stimulation Promotes Cardiac Differentiation of Human Induced Pluripotent Stem Cells

Figure 2

Custom made electrical stimulator. (a) A panel of 16 platinum-coated gold electrodes that fit into an 8-well chamber slide. Each well contained a pair of electrodes to stimulate the EBs in suspension. (b) Representative oscilloscope diagram of a pair of electrodes (at 200 mV/mm of the electric field) showing a charge-balanced biphasic current pulse (red) and the corresponding electrode voltage (yellow). Each current pulse was 1 ms/phase and was stimulated at 1 Hz. EB: embryoid body.
