This review article attempts to picture the state of the art of the SCs life span and their engagement in muscle regeneration and hypertrophy in exercise. Physiological activators such as exercise 15 , mechanical stretches 14 , 23 , and aging 24 , 26 , as well as pathologic conditions such as Duchenne muscular dystrophy 2 , 27 and irradiation 24 , 28 affect SC quiescence, their numbers, activation, and differentiation states through multiple signaling pathways. In order to unravel the complexity of this subject, SCs heterogeneity in an individual, both in number and spatial distribution within various skeletal muscles, is a tremendous challenge in this field, which is not attended due to lack of empirical data. Differences in the developmental fate of cultured and noncultured myoblasts when transplanted into embryonic limbs. Open in a separate window. Of note, simultaneous RT and ET increases SC numbers with subsequent enhancement of muscle mass and myonuclei 37 , 43 , mature muscle Since then, there is tremendous interest to investigate their application in muscle regeneration and repair due to their special self-renewal and multi-differentiation capabilities 2. Creatine supplementation augments the increase in satellite cell and myonuclei number in human skeletal muscle induced by strength training. Mourkioti F, Rosenthal N. It can be asserted that as with other modalities of exercises, an undetermined threshold exists for volume of the RE mode beyond which RE intervention induces SCs activation. The minimal threshold of RE intensity for SCs activation remains unidentified.

However, rodent and human skeletal muscles host SCs that possess different features. Eur J Appl Physiol. The authors did not directly measure the SC markers. Endurance training in humans: However, they observed that late stages of muscle differentiation were morphologically and functionally indistinguishable from other myofibrils. Exercise intensity is believed to be one of the most detrimental functional factors that modify SCs response to RE. Muscle samples were taken from the soleus muscle, a predominantly slow muscle which possesses greater resting SC levels and is less responsive to training compared to fast muscles Anderson J, Pilipowicz O. A quantitative study of satellite cells in regenerated soleus and extensor digitorum longus muscles. Finally, the type of muscle contraction can modulate SCs response to exercise. However, these SCs have no normal proliferation capacity and undergo apoptosis 11 which demonstrates the importance of PAX7 roles in normal SC behavior and skeletal muscle regeneration Satellite cells express distinct patterns of myogenic proteins in immature skeletal muscle. Time and intensity of exercise are important contributing factors in SCs activation. Bazgir B, Asgari A. It is suggested that SC addition to skeletal muscle fibers positively promotes muscle hypertrophy Inhibition of myostatin signaling through Notch activation following acute resistance exercise. It has clearly been demonstrated that increased muscle activity augments SC proliferation 15 whereas muscle inactivity decreases SCs proliferation Darr KC, Schultz E. Endurance training in humans: Postexercise myogenic gene expression: Acute molecular responses to concurrent resistance and high intensity interval exercise in untrained skeletal muscle. Daizha morgann anal cell involvement in muscle hypertrophy It is suggested that SC addition to skeletal muscle fibers positively promotes anal sex creampies hypertrophy In summary, SCs in response to different types of stimuli or under the control of MRFs can be activated, proliferated, differentiated, and ultimately participate in muscle regeneration. mature muscle
