From: Complex and dynamic patterns of Wnt pathway gene expression in the developing chick forebrain
Broader expression in the dorsal half of the forebrain - Wnt3A , Wnt3 and Wnt4. (A-I) Expression of Wnt3A (A-C), Wnt3 (D-F) and Wnt4 (G-I) at HH13 (A,D), HH14 (G), HH16 (B,E,H) and HH20 (C,F,I). Lateral views of whole mount (A,D,G) or hemisected brains (B,C,E,F,H,I) are shown; anterior points to the right. Note the expression of Wnt3A in the thalamus from HH13 onwards (arrowheads, A,B). Note the absence of clear Wnt3/3A expression from the dorsal pallium (arrowheads, C,F). Arrows mark the position of the zona limitans intrathalamica in (C,F,I). The arrowhead in (I) marks the epiphysis. Scale bars represent 0.2 mm.
