TS26: olfactory nerve	Present	Single cells	3D , 3C	Expression is seen in the entheathing cells surrounding nerve bundles in the olfatory nerve fiber layer, ie the Schwann cells. It is also localized to long fibrous bands in the nerve fiber layer.
TS26: nasal mesenchyme	Present		3C
TS26: nasal septum cartilage	Present	Non-Uniform	3D , 3C	Staining of chondrocytes in the nasal cartilage is decreased (weak) while strong staining remains in the perichondrium.

Structure	Level	Pattern	Image	Note
TS27: olfactory nerve	Present		3E , 3F	Expression is seen in the nerve fiber layer; it is observed in fibers that appear to be demarcating axon fasicicles in the olfactory nerve. There is weak expression in most cells, but some cells and fibrous bands have stronger staining.
