Fig1. Expression patterns of HoxA1 and HoxD1. Expression was examined by whole mount in situ hybridization as described under Materials and Methods. In all cases anterior is left. (A) HoxA1 expression: mid-neurula (Stage 15) lateral view. Black arrows, anterior and posterior boundaries of HoxA1 expression. (B) HoxA1 expression: mid-neurula (stage 17) dorsal view. sc, spinal cord; arrows, anterior and posterior boundaries of expression. (C) HoxA1 expression: tailbud (stage 24), lateral view. sc, spinal cord; arrow, anterior boundary of spinal cord expression. (D) HoxA1 expression: late tailbud (stage 30), lateral view. el, endolymphatic duct; hb, hindbrain; mb, midbrain. (Inset) HoxA1 expression relative to en-2. Closed arrows, HoxA1 expression; open arrow, en-2 expression. (E) HoxD1 expression: mid gastrula (stage 11) dorsal view. bp, blastopore; arrow dorsal lip. (F) HoxD1 expression: mid gastrula (stage 11), ventral view. (G) HoxD1 expression: early neurula (stage 13), dorsal view. (H) HOXD1 early neurula (stage 13), lateral view.(I) HoxD1 expression: mid neurula (stage 16), dorsal view. (J) HoxD1 expression: mid neural (stage 16), lateral view. Arrow, anterior boundary of expression. |
