Myoblasts are specialized cells that play a crucial role in the development of muscle tissue. They are a type of stem cell that can differentiate into muscle fibers, which are essential for movement and strength in the body. Myoblasts multiply and fuse together to form long, multinucleated cells known as myotubes, which eventually mature into functional muscle fibers. These cells are primarily found in developing embryos but can also be activated in adults during muscle repair and regeneration. Myoblasts respond to various signals in the body, including growth factors, to initiate the process of muscle formation and healing after injury.
