ABSTRACT
Objective@#To establish the isolation and culture methods of skeletal muscle stem cells, derived from human orbicularis oculi muscle (OOMSCs), and to identify their multi-directional differentiation potential in vitro.@*Methods@#The cellswere isolated from pretarsal orbicularis oculi muscle (OOM), obtained in routine blepharoplasty surgery.The tissue was digested using collagenase type I combined with re-plating methods. Specific cell surface antigen markers were detected using flow cytometry analysis. OOMSCs were cultured under different inductive conditions, to identify their pluripotent differentiation ability.@*Results@#OOMSCs exhibited similar fibroblast-like morphology as mesenchymal stem cells with high expression of skeletal muscle-derived stem cell surface markers. OOMSCs were able to differentiate into adipocytes, osteoblasts and chondrocytes in vitro, in the presence of lineage-specific inductive media. Moreover, after myogenic induction, the differentiated cells were fused into multinucleated myotube-like structure, and positive for myogenic-related marks, Pax3, Pax7, Myf5 and MyoD.@*Conclusions@#Muscle-derived stem cells can be isolated from human OOM with myogenic differentiation properties, showing further applications potential intissue regeneration and medical therapies of muscle diseases.
