Cardiomyocytes are specialized cells found in the heart that are responsible for contraction and pumping blood throughout the body. Research in this area focuses on understanding the structure, function, and regulation of cardiomyocytes in healthy and diseased hearts. This research is important for developing new treatments for heart conditions such as heart failure, arrhythmias, and heart attacks. Techniques such as stem cell therapy, gene editing, and tissue engineering are being used to study and manipulate cardiomyocytes in order to improve heart function and overall cardiovascular health.
