Figure 5. Diagrams illustrating the tissue transplantation experiment performed to localize Psf2 function in the eye. This experiment involves reciprocal transplantation of stage 14 presumptive lens ectoderm (ple) between uninjected embryos (upper example) and morpholino (MO)-injected embryos (lower example). Single blastomeres were injected with morpholino at the four-cell stage as shown. Green color shows the distribution of the co-injected morpholino and GFP RNA tracer. See text for further details.
