Bone marrow is one of the main sources of multipotent stem cells, composed by hematopoietic stem cells responsible for the renewal of the cellular components of the blood,

Compelling evidence indicates that adult satellite cells rep- resent a heterogeneous population of stem cells and com- mitted myogenic progenitors in skeletal muscle. At the
