The absence of nodal sprouts from partially denervated nerve trunks.

Nodal sprouts were absent from partially denervated, silver-stained, mouse superior gluteal (SG) nerves examined between 4 and 20 days after partial denervation. Nodal sprouts were also absent from electron micrographs of partially denervated SG nerves. We conclude that an earlier report describing profuse nodal sprouting in partially denervated nerve trunks mistakenly identified fine Schwann cell processes as nodal sprouts.
