Fig. 6. In situ hybridization analysis of dHAND, eHAND and Dlx6
transcripts in wild-type (A,D,F,H),
+neoBAenh/ (B,E,G,I) and
neoBAenh/ (C) embryos at E10.5.
dHAND (A,B,C,D,E), eHAND (F,G) and Dlx6 (H,I)
transcripts were detected by in situ hybridization to transverse (A-C,F-H) or
sagittal (D,E) sections. Note that ventrolateral dHAND expression in
the first branchial arch of mutant embryos was absent (arrows in B,C,E),
whereas heart expression was not affected (h in E). Branchial arches 1 and 2
are indicated.
