Analyses of target reinnervation. The density of axonal bundles was estimated in semi-thin sections of foot pad dermis (Left) and flexor plantaris muscle (Right). In the upper graphs, the density of axonal bundles per 10,000 μm² is indicated for unoperated nerves (control), and operated transgenic (PNT-1) and wild-type mice 5 weeks after nerve injury (n = 4). The lower micrographs show examples of semi-thin sections of dermis and muscle. Axonal bundles are indicated by arrows. (Bar = 10 μm.)
