Extracellular Recordings of Patterned Human Pluripotent Stem Cell-Derived Cardiomyocytes on Aligned Fibers
Extracellular recording of IMR hiPS-cardiomyocytes (CMs) by MEA at day 6. Spontaneous beatings of CMs on aligned fiber- (AF-) covered (a) and gelatin-coated (Flat) MEA (b) at day 6. (c) Premature beating recorded on Flat samples at day 6. The red arrows mark the representative beating of the premature beating. (d) Premature beating rate of samples at day 6. is the number of the respective samples. (e) Amplitude of field potential recorded on CMs at day 6 (means ± s.e., , ).
