Objective To study the effects of Schwann cell-derived neurotrophic factor(SDNF) on myoblast stem cells(called satellite cells,SCs) in vitro. Methods After setting up SCs culture system in vitro, SCs which treated with various SDNF concentrations culture medium were dynamically evaluated by cell morphology,MTT growth curve and fusion rate. Results The ability of SCs preceding their participation in muscle repair include proliferation and differentiation, 200 ng/ml SDNF stimulated cell proliferation more than the other medium,but 50 ng/ml,100 ng/ml,200 ng/ml,400 ng/ml SDNF made SCs differentiation significantly for their high myotube fusion rate. Conclusion SDNF can regulate the proliferation and differentiation of rat skeletal satellite cellsin vitro,but in differentiation significantly.SDNF might play a role in slowing down denervated muscle atrophy.
