Fig. 3. dHAND expression in staged Xenopus embryos. Whole-mount in situ hybridization in Xenopus embryos revealed dHAND expression in punctate subepidermal cells (arrowheads) as early as stage 20 (A). The punctate cells later appeared to be migrating to the branchial arches and heart (C). dHAND expression was observed in the branchial arches throughout their development (C–E). dHAND was expressed bilaterally in the lateral plate mesoderm (lpm) at stage 24 through stage 33 (B–D). High magnification of the anterior embryo better demonstrated expression in the looped heart tube and branchial arches at stage 37 (E). Even higher magnification of the cardiac region (F) demonstrated expression in the heart tube (ht) and outflow tract (ot) at stage 47 without any chamber restriction. |
