Sdf-1 impacts on the expression of adhesion proteins (m-cadherin, ADAM-12, syndecan-4, CD9, CD81, integrin β1, integrin α3, integrin α7, integrin α9) in differentiating rat satellite cell-derived myoblasts. (A) Level of mRNA at days 5 and 7 of control (C) and Sdf-1-treated myoblast (Sdf-1) differentiation. (B) Immunolocalisation of adhesion proteins in control and Sdf-1-treated cells. Nuclei, blue; adhesion proteins, green. Bar = 20 μm. (C) Level of adhesion proteins during control and Sdf-1-treated myoblast differentiation at day 7. itgb1, integrin β1; itga3, integrin α3; itga7, integrin α7; itga9, integrin α9. *P <0.05.
