Expression of Wnt16 genes. Expression of of Wnt16 in Parasteatoda (A–D), Pholcus (E–H), Acanthoscurria (I–M) and Phalangium (N–S). In all panels, anterior is to the left. Panels A, D, E, F, and S represent lateral views. Other panels represent ventral views, except panel M (dorsal view). The inlay in panel M shows the saz of the the same embryo (ventral view). The inlay in H shows a lateral view on the tail and the saz. Panel I´ represents SYBR-green staining of the embryo shown in I. Arrow and arrowheads in panel D point to expression along the dorsal rim of the prosoma and dorsally in the opisthosoma, respectively. Developmental stages are indicated. Arrowheads in panels H, M, and S point to dorsal expression in the opisthosoma. Asterisks in panels J and K mark expression ventral to the base of the limbs. Expression patterns are summarized in panel T; anterior is up. Abbreviations as in Fig. 4
