Figure Caption
Fig. 5
Cell morphology and cell migration are rescued by restoring Spadetail. (A) Cells in the hypoblast of spt morphant cells expressing spt after transgene induction blebbed less frequently than with morpholino alone (see Fig. 2B for quantification). (B) When spt morphant cells were transplanted into the ventral mesoderm of a wild-type embryo at shield stage they were unable to contribute to somites. (C) Restoring Spadetail by inducing transgene expression allowed cells to migrate out of the tailbud and contribute to developing somites. Each panel is representative of at least 16 successful transplants.
