Coexpression of GAP-43 and SCG10 mRNAs in layers II and III of the LGN. A, Localization of GAP-43 mRNA.B, Localization of SCG10 mRNA in the same section asA. C, The image of B was superimposed on the image of A. Most of the neurons contained the hybridization signals for both GAP-43 mRNA (dark blue) and SCG10 mRNA (green). In some neurons, the signal was selective for GAP-43 mRNA (arrows) or SCG10 mRNA (arrowheads). Scale bar, 100 μm.
