Figure 7. Retina histological analysis of voltage-gated calcium channel (VGCC) alpha 1 subunit expression in stage 40 (swimming tadpole) X. laevis using whole-mount in situ hybridization. A-G: Transverse 18- mu m sections of the retina, with dorsal to the top. A: CaV1.2 expression. B: CaV1.3 expression. C: CaV1.4 expression. D: CaV2.1 expression. E: CaV2.2 expression. F: CaV3.1 expression. G: CaV3.2 expression. Brackets indicate retinal layers with expression. GCL, ganglion cell layer; INL, inner nuclear layer; L, lens; PR, photoreceptor cells. Scale bar = 0.1 mm. |
