meis1.1 and hoxa11b expression in zebrafish fins. af Dorsal, g, h anal and il pelvic fins. ad, f, h, il WISH and e, g Alcian Blue staining followed by WISH. ac, e, g, h Arrowheads indicate fin mesenchyme cells expressing meis1.1 and hoxa11b. c The white arrow indicates unsegmented radial; c the black arrows indicate WISH staining in dorsal somite cells. ad, j, l The dashed lines indicate distal limit of endochondrogenic mesoderm below the finfold in ad dorsal and j, l pelvic fins. eh The solid lines indicate the boundary between proximal and distal radials in e, f dorsal and g, h anal fins. af, il Anterior to left, distal to top; g, h anterior to left, distal to bottom. Fish length is ac 3.6–4.4 mm, d 4.0–5.2 mm, eh 5.6–6.1 mm, i, k 4.1–5.3 mm, j, l 5.0–6.4 mm. Abbreviations: dr, distal radial; pr, proximal radial. Scale bars are 100 μm (a, b, f, g), 50 μm (ce, hl), and 70 μm (kn)
