Fig. 6. sp5l MO enhances wnt3a loss of function. Embryos were injected with 3.5 mg/ml control morpholino (A,B), 2.5 mg/ml sp5l MO + 1 mg/ml control MO (C,D), 1 mg/ml wnt3a MO +2.5 mg/ml control MO (E,F), or 1 mg/ml wnt3a MO + 2.5 mg/ml sp5l MO (G, H). (A,C,E,G) Live embryos are shown at 48 hpf, anterior to the left. (B,D,F,H) Embryos stained for tbx6 expression at the 10-somite stage and shown in a dorsal view of the tailbud region, anterior to the top.
