Fig. 7
fgf10a is expressed around the Pdx1+ domain. (A,D) fgf10a in situ hybridization combined with anti-GFP immunostaining in Tg(gutGFP) embryos reveals fgf10a expression around the endoderm directly caudal to the liver-forming region at 30 (A) and 36 (D) hpf. (B,E) Comparison with the Prox1 and Pdx1 expression pattern at these stages suggests that fgf10a is expressed around the Pdx1+ domain. (C,F) The expression patterns of Prox1 (red), Pdx1 (green) and fgf10a (blue) at these stages. Broken lines outline the dorsal pancreas; brackets mark the liver-forming region. Ventral views, anterior up. Scale bar: 50 μm.
