Cardiomyocytes are the muscle cells of the heart responsible for contraction and pumping blood throughout the body. Research in this area focuses on understanding the structure, function, and regulation of these cells in both healthy and diseased states. Scientists study various aspects of cardiomyocytes, such as their development, physiology, metabolism, and response to injury or stress. This research is important for advancing our knowledge of cardiovascular diseases, such as heart failure, arrhythmias, and myocardial infarction, and developing new treatments and therapies to improve heart health.
