Figure 8From: Duplicate dmbx1genes regulate progenitor cell cycle and differentiation during zebrafish midbrain and retinal developmentCumulative BrdU labelling reveals an increase in the morphant progenitor cell cycle in the 72 hpf retina. (A-F) Immunolabelled coronal sections (dorsal to the top, lens to the left) from embryos repeatedly injected with BrdU (red) after different survival times (indicated on the left). Sections were counter-stained with DAPI (blue). (G, H) Regression analyses from cumulative labelling data. MO, morpholino; hpf, hours post-fertilization, hr, hours.Back to article page
