Fig. 7. The homeodomain transcription factor Meox2 does not control Myf5
expression in myogenic progenitor cells in the limb. Wild type
(A-C,G-I) and Meox2-null mutant (D-F,J-L) embryos
carrying the transgenes Myf4-IV (A-F) or BAC195APZ (G-L) display very similar
expression of either transgene in fore- and hind limbs between E11.5 and 13.5.
Note, however, that distinct muscles in limbs of homozygous Meox2 mutants are
missing.
