Abstract

The protocol described here efficiently directs human pluripotent stem cells (hPSCs) to functional cardiomyocytes in a completely defined, growth factor- and serum-free system by temporal modulation of regulators of canonical Wnt signaling. Appropriate temporal application of a glycogen synthase kinase 3 (GSK3) inhibitor combined with the expression of β-catenin shRNA or a chemical Wnt inhibitor is sufficient to produce a high yield (0.8-1.3 million cardiomyocytes per cm(2)) of virtually pure (80-98%) functional cardiomyocytes in 14 d from multiple hPSC lines without cell sorting or selection. Qualitative (immunostaining) and quantitative (flow cytometry) characterization of differentiated cells is described to assess the expression of cardiac transcription factors and myofilament proteins. Flow cytometry of BrdU incorporation or Ki67 expression in conjunction with cardiac sarcomere myosin protein expression can be used to determine the proliferative capacity of hPSC-derived cardiomyocytes. Functional human cardiomyocytes differentiated via these protocols may constitute a potential cell source for heart disease modeling, drug screening and cell-based therapeutic applications.

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.
