Fig. 3. WtIGFBP-5 and mutIGFBP-5 increase myoblast cell number but do not change proliferation rate. (A) Cell number, expressed as percentage of cells in GM compared with DM, in myoblasts transfected with control vector, wtIGFBP-5 (wtBP5) or mutIGFBP-5 (mutBP5); means±s.e.m.; n=3. (B) BrdU incorporation into myoblasts transfected as in A; mean±s.e.m., n=3.
