Fig. 2From: Characterization of primary cilia during the differentiation of retinal ganglion cells in the zebrafishPrimary cilia emerging from the basolateral membrane of retinal neuroepithelial cells. TEM micrographs of retinas from 26 and 35 hpf embryos. a Low magnification (left) and high magnification serial sections (right) of a retina from a 35 hpf embryo. A primary cilium emerges from the basolateral membrane, as evidenced by the presence of adherent junctions (AJ). b Basal body without an axoneme, but closely associated with the basolateral membrane. c Basal body with a short axoneme inside a cytoplasmic vesicle. d Low magnification (left) and high magnification serial sections (right) of a retina from a 26 hpf embryo showing a primary cilium emerging from the basolateral membrane. White arrowhead: basal body; RPE: retinal pigment epithelium. Scale bars: A-D, 1 μm. For a high resolution image of Fig. 2 please see Additional file 13 Back to article page
