Fig. 5 Pax3 and Pax7 are redundantly required for migrating muscle progenitor (MMP) myogenesis. Dorsal view showing the expression of myogenin (myog) (left column), ladybird homeobox 1a (lbx1a) (middle column) and met (right column) in A-C wt (n = 47), D-F, pax3a−/−/3b−/− (n = 33), G-I, pax7a−/−/7b−/− (n = 13), J-L, pax3a−/−/3b−/−/7a−/− (n = 13), M-O, pax3a−/−/3b−/−/7b−/−(n = 16), P-R, pax3a−/−/7a−/−/7b−/− (n = 12), S-U, pax3b−/−/7a−/−/7b−/− (n = 33), and V-X, pax3a−/−/3b−/−/7a−/−/7b−/− (n = 7) mutant zebrafish embryos at 48 hpf. Arrowheads indicate abductor, adductor, sternohyoideus, and posterior hypaxial muscle, or fin bud where impossible to distinguish between abductor/adductor. abd, abductor; add, adductor; fb, fin bud; sh, sternohyoideus; phm, posterior hypaxial muscle.
