  1. 2 ng of either wnt-5 translation-blocking or exon-intron junction targeting morpholinos were injected into either wild-type embryos or embryos generated from an outcross of a wnt-5 mutant carrier adult. In wild-type embryos, injection of either wnt-5 MO resulted in less than 5% of embryos with scattered insulin expression. However, injection of either wnt-5 MO resulted in about 50% of embryos with scattered insulin expression in embryos obtained from the wnt-5 mutant carrier outcross.
