Fig. 4.
mtx2 morpholinos inhibit epiboly. All views are lateral with dorsal to the right; all embryos are at shield stage (6 hours postfertilization). Injected construct, if any, is indicated in lower left corner. A: Uninjected embryo. B: Embryo injected with Mtx2-MO1 into one cell at the two-cell stage; note that the blastoderm is thickened compared with control. C: Embryo injected with Mtx2-MO1 into the yolk syncytial layer (YSL); note that the blastoderm is thickened compared with control.
