H9c2(2-1) Cells

H9c2(2-1) cells, derived from the ventricular myoblasts of embryonic BD1X rat hearts, are a subclone of the original H9 cell line established in the early 1990s. These cells are immortalized myoblasts that are commonly used in vitro to study cardiac metabolism, physiology, and pathophysiology, including myocardial ischemia, hypertrophy, and apoptosis mechanisms. Phenotypically, H9c2 cells exhibit characteristics of skeletal muscle but retain the ability to adopt a cardiac muscle phenotype under specific experimental conditions, such as differentiation induced by retinoic acid or other agents. This flexibility makes them a valuable model for investigating cardiac muscle behavior in response to various physiological and pharmacological stimuli. Genetically, H9c2 cells are diploid, facilitating their use in genetic studies, where maintaining a stable karyotype is crucial. Research employing H9c2(2-1) cells has contributed significantly to understanding cellular responses to oxidative stress, mitochondrial dysfunction, and the protective roles of various pharmacological agents against cardiotoxicity. This cell line remains a cornerstone in cardiomyocyte-related research, offering a reproducible, controlled model to elucidate the complex biological and molecular mechanisms underlying cardiac function and diseases.
