Figure 2From: Zebrafish Ext2 is necessary for Fgf and Wnt signaling, but not for Hh signalingReduced expression of eng1a and fgf8a in MHB but normal eng1a expression in muscle pioneers. Lateral view (A, C, E-H) and dorsal view (B, D) of 38 hpf (A-D) and 48 hpf (E-H) embryos. Expression of eng1a and fgf8a in ext2 mutants (C, D, F, H) and WT embryos (A, B, E, G). The arrows label the MHB and arrowheads label muscle pioneer cells.Back to article page
