Fig. 6. Secretory responsiveness develops in the absence of cholinergic
innervation. Sweating response in P60 mice after intraperitoneal injection
of pilocarpine. (A,B) The glands in both control
gp130fl/fl (A) and gp130DBHcre (B)
footpads respond robustly to the pilocarpine treatment. Each pore, which
appears as dark spot, represents the activity of a single gland. (C)
Quantification of the number of active glands/per interdigital footpad. Data
are presented as mean±s.e.m. of 12 control and six
gp130DBHcre mice. The difference between
gp130fl/fl and gp130DBHcre
mice is significant (P<0.05; unpaired, two-tailed
t-test).
