Figure 6.

Electron microscopic analysis of sciatic nerves. Electron micrographs of the sciatic nerves from Adam22 +/- (A) and Adam22 -/- (B) mice at postnatal day 10 are shown. In the heterozygote (A), thick myelin was formed, while no myelin was formed in the ADAM22-deficient mouse (B). The axons looked normal in each genotype.
