PG - 3887-94 AB - To investigate the influences of growth factors on axonal regeneration in the mammalian CNS, we used intracellular tracers to quantitate the effects of brain-derived neurotrophic factor (BDNF), neurotrophin (NT)-4/5, or NT-3 on individual retinal ganglion cell (RGC) axons in the retinas of adult rats after optic nerve transection. A single injection of BDNF or the prolonged administration of NT-4/5 by mini-pump increased axon branch median lengths by eightfold but had no effect on the number of branches formed by the RGC axons. NT-3 did not significantly influence axonal regrowth. These specific in vivo effects of BDNF and NT-4/5 on axonal regeneration from injured RGCs may be used to promote growth and expand the abnormally small terminal arbors observed when RGCs regrow into their CNS targets.
