Outgrowth distances from the point of nerve crush to the leading edge of the growing axons at 4 days, 5 days, and 7 days following injury in castrated male hamsters and castrated male hamsters given systemic testosterone treatment. Circles represent means and vertical lines represent SEMs. * = p < .05. Diagonal lines represent extrapolation of the data. Note that the data extrapolate to approximately 2 days post-injury for the zero outgrowth distance. This time point corresponds both to the androgen-induced spike in neuritin mRNA levels (see Section 3.4) and to the earliest time point at which androgen treatment augments tubulin upregulation following axotomy (Jones and Oblinger, 1994; Jones et al., 1999b). (After Kujawa et al., 1991.)
