Fig. 6. Localization studies in quiescent cells. (A-C) C2C12 myoblasts that were normally dividing, induced to become quiescent or subsequently reactivated for 24 hours, were fixed and labeled with the indicated antibodies. Similarly, dividing, quiescent and reactivated non-muscle cells (mouse C3H10T1/2 fibroblasts, bottom) were fixed and labeled with mAb LA-2H10. Scale bar: 10 µm.
