Skeletal muscle is the most abundant tissue in the human body and has a tremendous capability to regenerate in response to muscle injuries and diseases. Induction of acute muscle injury is a common method to study muscle regeneration in vivo. Cardiotoxin (CTX) belongs to the family of snake venom toxins and is one of the most common reagents to induce muscle injury. Intramuscular injection of CTX causes overwhelming muscle contraction and lysis of myofibers. The induced acute muscle injury triggers muscle regeneration, allowing in-depth studies on muscle regeneration. This protocol describes a detailed procedure of intramuscular injection of CTX to induce acute muscle injury that could be also applied in other mammalian models.
