Histological Characterization of the Dicer1 Mutant Zebrafish Retina

Figure 6

Ultrastructure of the photoreceptor layer of retina of Dicer1 mutant zebrafish. (a) Part of the photoreceptor layer showing inner and outer segments of cones and rods. The inner segment contains electron dense mega-mitochondria (MD), electron lucent mega-mitochondria (ML), and nucleus. (b) Part of the outer segment containing disc lamellae. (c) Magnified image inner segment containing electron lucent and electron dense mega-mitochondria and large nucleus. (d) Magnified image of MD containing electron dense cisternae. (e) Magnified image of cisternae of MD containing electron lucent spaces between cisternae. (f) Magnified image of ML containing electron lucent cisternae. IS: inner segment, MD: electron dens mega mitochondria, ML: electron lucent mega mitochondria, N: nucleus, OS: outer segment, PL: photoreceptor layer.
