Here, we report the isolation of progenitor cells from pig skeletal muscle tissue fragments. Muscle progenitor cells were stimulated to migrate from protease‐digested tissue fragments and cultured in the presence of 5 ng/ml basic fibroblast growth factor. The cells showed a sustained long‐term expansion capacity (>120 population doublings) while maintaining a normal karyotype. The proliferating progenitor cells expressed PAX3 , DESMIN , SMOOTH MUSCLE ACTIN , VIMENTIN , CD31 , NANOG and THY‐1 , while MYF5 and OCT3/4 were only expressed in the lower or higher cell passages. Myogenic differentiation of porcine progenitor cells was induced in a coculture system with murine C2C12 myoblasts resulting in the formation of myotubes. Further, the cells showed adipogenic and osteogenic lineage commitment when exposed to specific differentiation conditions. These observations were determined by Von Kossa and Oil‐Red‐O staining and confirmed by quantitative RT‐PCR analysis. In conclusion, the porcine muscle‐derived progenitor cells possess long‐term expansion capacity and a multilineage differentiation capacity. J. Cell.
