Figure Caption
Fig. 3 Pectoral fin development is affected in embryos compromised in Blimp-1 activity. (A) Normarski image of a wild-type fin. (B) Fin of a homozygous ubo mutant embryo. (C) Rudimentary fin bud of a blimp-1 morphant embryo. (D-F) Alcian blue stain of the pectoral fin skeletal elements of a wild-type, ubo mutant and blimp-1 morphant embryo. 1 = cleithrum, 2 = scapulocoracoid, 3 = endoskeletal disk, 4 = actinotrichs, 5 = postcoracoid process. All panels show lateral views.
