Moderate reduction of Fgf8a can rescue forelimb development in RA signaling-deficient embryos. (A) Forelimb (pectoral fin) of control sibling embryo. (B) Representative embryo treated with DEAB lacks forelimbs. (C) Representative embryo treated with DEAB and injected with 2 ng fgf8a MO mixture that has forelimbs. Views are lateral at 72 hpf. (D) Graph indicating the percentage of control sibling (n = 27) embryos, DEAB treated embryos (n = 34), and DEAB treated embryos that were also injected with 2 ng fgf8a MO mixture (n = 21) with forelimbs from a representative experiment. 100% (n = 13) of embryos injected with 2 ng fgf8a MO mixture had forelimbs (not shown). Injection of a 6 ng fgf8a MO mixture into DEAB treated embryos also restored fins as 63% (10 had forelimbs; n = 16).
