Neuronal BDNF Signaling Is Necessary for the Effects of Treadmill Exercise on Synaptic Stripping of Axotomized Motoneurons

Table 1

Groups and numbers of mice studied.

Group	Number of mice	Number of cells/mouse
Intact^*	11	10–20
Transected & unexercised^*	8	20
Transected & treadmill exercised^*	9	20
Intact SLICK::BDNF^f/f	5

WT mice.
Six WT and six KO cells were studied in each SLICK::BDNF^f/f KO mouse. All knockout mice were tamoxifen-treated.
