Answer:

-muscle precursor cells migrate from the somite to the regions of the embryo that will form muscles (limb buds)

-myogenic precursor cells express the paired homeodomain transcription factor, Pax3 and in some cases Pax7

-mutants lacking functional Pax3 have no limb muscles because of failure of muscle precursors to migrate from the somite to the limb bud

-Pax3/Pax7 positive cells are true stem cells in that they are capable of either self-renewal (proliferation) or differentiation to form committed muscle cells
