Heart development is the process by which the heart forms and matures during embryonic development. This intricate process involves the development of specialized cells and tissues that come together to form the structure of the heart, including the atria, ventricles, valves, and blood vessels. Research in this area aims to understand the genetic and molecular mechanisms that regulate heart development, as well as the role of environmental factors in influencing heart development. This knowledge is important for understanding congenital heart defects and developing new therapies for heart disease. Research in heart development also has implications for regenerative medicine, as scientists explore ways to repair damaged heart tissue and improve cardiac function.
