SOX10 Expression in the Human Embryonic Olfactory System

(A and B) Immunostaining of the head of a human fetus at 8 weeks of embryonic development (sagittal sections) at the level of the nasal mesenchyme (A) or migratory mass and olfactory bulb (B). Double labeling for SOX10 (green) and the neuronal marker (TUJ1; blue) and counterstaining with DAPI (blue) are shown. Abbreviations are as follows: M, mesenchyme; MM, migratory mass; OB, olfactory bulb; and OE, olfactory epithelium.

(C) Immunostaining showing an olfactory nerve at higher magnification. Double staining for SOX10 (green) and the OEC marker (S100; red) and counterstaining with DAPI are shown.
