Abstract

In view of the therapeutic potential of cardiomyocytes derived from induced pluripotent stem (iPS) cells (iPS‐derived cardiomyocytes), in the present study we investigated in iPS‐derived cardiomyocytes, the functional properties related to [Ca 2+]i handling and contraction, the contribution of the sarcoplasmic reticulum (SR) Ca 2+ release to contraction and the b‐adrenergic inotropic responsiveness. The two iPS clones investigated here were generated through infection of human foreskin fibroblasts (HFF) with retroviruses containing the four human genes: OCT4, Sox2, Klf4 and C‐Myc. Our major findings showed that iPS‐derived cardiomyocytes: (i) express cardiac specific RNA and proteins; (ii) exhibit negative force–frequency relations and mild (compared to adult) post‐rest potentiation; (iii) respond to ryanodine and caffeine, albeit less than adult cardiomyocytes, and express the SR‐Ca 2+ handling proteins ryanodine receptor and calsequestrin. Hence, this study demonstrates that in our cardiomyocytes clones differentiated from HFF‐derived iPS, the functional properties related to excitation–contraction coupling, resemble in part those of adult cardiomyocytes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
