Generating cardiomyocytes from pluripotent stem cells in vitro allows access to large amounts of cardiac tissue in vitro for basic science and clinical applications. This protocol uses the atrializing factor Grem2 to both increase the numbers of cardiomyocytes obtained and to generate cardiomyocytes with an atrial phenotype.

Electrophysiological characterization of cardiomyocytes derived from human Pluripotent Stem Cells (hPSC-CMs) is crucial for cardiac disease modeling and for determining drug responses. This protocol provides the necessary information to dissociate and plate hPSC-CMs on multi-electrode arrays, measure their field potential, and a method for analyzing QT and RR intervals.

The cardiac biowire platform is an in vitro method used to mature human embryonic and induced pluripotent stem cell-derived cardiomyocytes (hPSC-CM) by combining three-dimensional cell cultivation with electrical stimulation. This manuscript presents the detailed setup of the cardiac biowire platform.
FAQs
Timed changes in developmental signals first encourage pluripotent stem cells toward mesoderm, an early embryonic tissue layer, and then promote cardiac cell fate. The sequence matters because differentiation depends on changing signals during development rather than exposing cells to one unchanging condition. This strategy helps generate populations suitable for cardiac biology and disease studies.
Laboratory-generated cardiomyocytes may remain less mature than adult heart muscle cells, limiting how closely their structure and electrical behavior represent the adult heart. Culture conditions can be adjusted to improve these properties. Greater structural and electrical maturity strengthens their usefulness for interpreting disease-related changes, assessing drug effects, and advancing regenerative research.
The key distinction is their degree of structural and electrical maturity. Cells produced in the laboratory can display cardiac characteristics yet still differ from adult heart cells in how fully those properties have developed. This limitation affects how findings are interpreted, making maturation an important consideration when using them as models of cardiac biology or disease.
Production generally begins with pluripotent stem cells and proceeds through timed changes in developmental signals. Early conditions direct cells toward mesoderm, followed by signals that specify cardiac cell fate. After differentiation, culture conditions support further maturation, with attention to improving structural and electrical properties before the cells are used in experiments.
Researchers can use these cells to investigate both inherited and acquired cardiac disorders. Because the cells provide a renewable laboratory model, experiments can examine disease-related cardiac biology under controlled culture conditions. Their value is especially relevant when studying how developmental cardiac processes or cellular properties are altered in disease models.
In medicine-focused research, Stem Cell Cardiomyocytes can help evaluate drug effects and toxicity while also providing a model for cardiac development and disease. They may support investigations of tissue repair, although their incomplete maturity remains an important limitation. Improving their structural and electrical characteristics could increase their relevance to regenerative applications and therapeutic research.
