Cardiac NAM Implementation Methods
The following technical methods illustrate practical implementation approaches relevant to cardiac NAM applications, including organoid culture, engineered tissues, and 3D cardiac microenvironments compatible with disease modelling and drug screening. A cardiac NAM platform is only as valuable as its methodological robustness. Key evaluation dimensions include reproducibility, multicellular fidelity, mechanistic resolution, and translational interpretability.
