Expression of Wnt6 genes. Expression of Wnt6 in Parasteatoda (A–D), Pholcus (E–I), Acanthoscurria (J–M) and Phalangium (N–S). Panels C, G, J, L, N, R and S show ventral views. Panels I and M show dorsal views. Panels A, B, D, E, F, H, K, and O–Q show lateral views. Developmental stages are indicated. In all panels, asterisks (*) mark dorsal stripes of expression and expression in the forming heart, arrows and arrowheads point to expression in the ventral nervous system and the dorsal rim of the prosoma, respectively. Filled circles in panel U mark segmental stripes of expression in the ventral sulcus. Expression patterns are summarized in panel T, anterior is up. Abbreviations as in Fig. 4; and bl, book lungs
