This tissue has the ability to regenerate after minor injuries, a process facilitated by resident muscle stem cells that help to build new muscle fibers. However, acute muscle loss (which can happen in severe accidents), progressive muscle loss, or genetic diseases, such as muscular dystrophy, may compromise this tissue repair process. In these cases, patients can experience mobility issues and...
