Abstract:
BACKGROUND:Skeletal muscle satelite cels are muscle-derived stem cels with proliferation and differentiation potential distributing between the muscle cel membrane and the base film. Studies have shown that skeletal muscle satelite cels are of efficacy and safety, but the survival rate of the transplanted stem cels is very low, which greatly limits the application of skeletal muscle satelite cels. OBJECTIVE: To observe the effects of Fasudil on apoptosis of skeletal muscle satelite cels induced by H2O2. METHODS: Skeletal muscle satelite cels cultured in vitro were randomly divided into three groups including H2O2group, H2O2+Fasudil group (Fasudil group) and control group. Apoptosis rates were observed by flow cytometry. The concentrations of interleukin-4 and tumor necrosis factor-a in each group were detected by ELISA. Western blot was employed to measure the protein level of Bax in each group. RESULTS AND CONCLUSION: Compared with the H2O2group, a significant decrease was found in the apoptosis rate of cels, protein level of Bax, and concentrations of interleukin-4 and tumor necrosis factor-a in the Fasudil group (alP < 0.05). These findings indicate that Fasudil can play anti-apoptosis protection by inhibiting Rho-kinase signaling pathway, which may be related to the reduced expression of Bax.
