Migration of primary skeletal myoblasts. At 12 h after treatment with sildenafil, the number of myoblasts that migrated into the acellular area was counted. DMSO treatments were used as controls. The scale bar indicates 100 μm. The number of myoblasts in the acellular area was normalized to the DMSO control. Sixteen places per sample were examined, and the results are presented as the means±s.e. *, and the significant difference was compared with DMSO (P<0.05). The migration of primary skeletal myoblasts was significantly slowed by sildenafil.
