ONLINE COVER Twice Transplanted Muscles. A cross section of fibers from a mouse tibialis anterior muscle containing transplanted satellite cells labeled with green fluorescent protein (GFP) (green). The transplanted cells were themselves derived from a mouse into which GFP-labeled satellite cells had been transferred from a third donor mouse. As Hall et al. show, these cells are capable of extensive self-renewal through two serial transplants and are located under the basal lamina (red) of the muscle fibers. [CREDIT: J. K.
