Figure 4. Low and high power views of embryos after laser injection with QDs. (A) An uninjected (left) and laser-injected (right) embryo right after injection. (B) Control- and (C) laser-injected embryos photographed at the early gastrula stage, ∼8 h after injection. (D) Control- and (E) laser-injected embryos photographed at the tadpole stage, ∼3 d after injection. Note some nonspecific autofluorescence in the gut (arrows) of the control embryo but a higher level of fluorescence in the injected embryo. (F) Control- and (G) laser-injected embryos ∼2 days pf photographed in the gut region using the Nikon confocal microscope. Scale bars = 100 μm in A, F, and G and ∼1 mm in B –E. Under similar experimental conditions, four laser and one manually injected embryos with QDs were monitored and photographed, suggesting a higher level of fluorescence in the guts.
