Facial nucleus double fluorescent-labeling laser scanning confocal fluorescence microscopy: red indicates sonic hedgehog-positive cells (a); green indicates GFAP-positive cells (b). GFAP-positive cells did not express sonic hedgehog. Panel (c) was the merger of panel (a) and panel (b). Panel (d) is the 3D image of confocal imaging (c).
