Fig. 6. LvDelta function is required in both micromere and macromere derivatives. Cell transplantation was used to test the effects of blocking LvDelta function in either the micromere descendants or the macromere and mesomere descendants. (A-C) Micromeres containing LvDelta morpholino and a lineage tracer were combined with normal macromeres and mesomeres. (A) Diagram of the experimental design. The resulting embryos have few pigment cells (B), but anti-myosin staining of muscle fibers appears normal (C). (D-F) Macromeres and mesomeres containing LvDelta morpholino and a lineage tracer were combined with normal micromeres. (D) Diagram of the experimental design. The resulting larvae produce many pigment cells (E) but few muscle fibers (F).
