Fluorescent microscopy image of the cone cells of a gene-edited zebrafish (IMAGE)
Caption
Zebrafish eyes have cone cells specialized to differentiate near-ultraviolet (V), blue (B), green (G) and red (R) wavelengths of light. Researchers visualized the regular, repeated patterns of cone cells lined up beside each other in zebrafish eyes by adding different fluorescent tags to the specialized subtypes of cone cells (top) or to color-sensitive proteins within the cells (bottom). Experiments showed how blocking normal activity of the regulatory gene foxq2 (foxq2 mut) causes zebrafish to develop eyes without any of the blue-sensitive cone cells seen in healthy animals (wild type, WT). Scale bar: 50 micrometers.
