diI injection is described in Fig 5; r: frontal bone rudiment, a, apical mesenchyme.

Embryos were analyzed after 48 hours of exo utero development; e, ectocranial mesenchyme, b, prospective frontal bone.

Genotypes of control embryos were either wild type, or Wnt1-Cre; Msx1/2 double heterozygotes, which had no phenotype.
