CNP-Cre is selectively expressed in Schwann cells and oligodendrocytes but not neurons of the cochlear nucleus and spiral ganglion. Cross-sections of the peripheral segment of the cochlear nerve (A), spiral ganglion (B), and cochlear nucleus (C,D) from 2-week-old CNP-Cre-YFP-Rosa reporter mice were examined for the expression of yellow fluorescent protein (YFP). YFP was expressed by Schwann cells surrounding the cochlear nerve axons (*; A) and the SGNs (N; B) but was not detected in the axons (*) or neurons (N) themselves. Double labeling with APC (oligodendrocyte marker) and YFP showed complete overlap in the cochlear nucleus (C). In contrast, double labeling with NeuN (neuron marker) and YFP showed no overlap (D). Three mice were analyzed with similar results. Representative image is shown. Site at which sections were cut as referenced in Figure 2 are A: 2; B: 3; C,D: 5. Scale bars = 10 μm in A; 20 μm in B, insets; 100 μm in C,D.
