Functional analysis of mutant pitx2HD transcripts. (A) RNA in situ hybridizations revealed normal pitx2 mRNA expression in wild-type, pitx2HD-/- and pitx2c-/- embryos, including asymmetric pitx2c in lateral plate mesoderm (arrow) at the 18 somite stage (18 ss). L=left; R=right. (B) Microinjection of wild-type pitx2c mRNA into wild-type embryos resulted in severe developmental defects or lethality at 2 dpf, which was not frequently observed in controls injected with gfp mRNA. Most embryos injected with pitx2c mRNA containing the HDsny15 mutation developed normally. n=number of embryos analyzed (pooled from three experiments).
