Figure 4. Retinal histological analysis of GABA receptor subunit expression in swimming tadpole (stage 40) X. laevis embryos. Transverse 18-μm sections of the retina, with dorsal to the top. Brackets, retinal layers with expression; black triangles, ganglion cells; white triangles, horizontal cells; black arrows, amacrine cells. A: GABAAα1 expression. B: GABAAα2 expression. C: GABAAα6 expression (*stage 35). D: GABAB1 expression. E: GABAB2 expression. GCL, ganglion cell layer; INL, inner nuclear layer; L, lens; PR, photoreceptor layer. Scale bar = 0.1 mm.Download figure to PowerPoint |
