Abstract: Porcine skeletal muscle is an important movement organization of animal body,the main meat source of human beings,and a good model for muscle growth and disease research.After birth,pig needs the participation of muscle satellite cells in the growth and development of skeletal muscle,and the damage repair.Isolation and culture of porcine skeletal muscle satellite cells in vitro is the basis for in-depth study on the growth and development of skeletal muscle and the pathogenesis of diseases,and the premise for molecular function verification at the cellular level.With the deepening of the research on muscle development and pathological molecular mechanism,the technology of isolation and culture of satellite cells of porcine skeletal muscle in vitro has developed rapidly.The longissimus dorsi muscle,hind leg muscle and semitendinosus muscle are commonly used to isolate skeletal muscle satellite cells,and the longissimus dorsi muscle of 1-day-old piglets have the best isolation effect.Enzymes commonly used to isolate skeletal muscle satellite cells include pronase,collagenase,trypsin,collagenase,etc.,and the time of digestion of each enzyme and its combination is different.The best filtration method is 200 mesh +400 mesh combined filtration,and high purity cells can be obtained by three times centrifugation.The usual medium is DMEM/F12+10% fetal bovine serum (FBS)+1% penicillin-streptomycin (P/S).Common markers of skeletal muscle satellite cells include pairing box gene 3(PAX3),PAX7,Myo-genic determinant 5(Myf5),Myf4,Myo-differentiation factor (MyoD),myogenin (MyoG) and so on.In this paper,the isolation,culture and identification of muscle satellite cells of porcine skeletal muscle were reviewed,and the best parameters in each step were sorted out,which provided references for establishing a standardized procedure for isolating porcine skeletal muscle satellite cells,in order to provide theoretical and technical support for muscle development and disease research.
