Fig. 7 Treatment with SB-505124 after MBT enhances the MZoep mutant phenotype. MZoep mutants were treated with DMSO (A, C), SB-431542 at the 16- to 32-cell stage (B), or SB-505124 at 3 hpf (D). The majority of MZoep mutants treated with DMSO develop long tails containing somites (A), but a minority has underdeveloped tails with no apparent somites (C). After treatment with SB-431542 during the cleavage stages, all MZoep mutants have shortened tails with no apparent somites (B). Similarly, MZoep mutants have short tails after treatment with SB-505124 at 3 hpf (D). Images of live embryos at 24 h, anterior to the left.
