Circuitous growth pattern at brain-derived neurotrophic factor (BDNF) delivery site. (A) Low-power photo of BNDF cuffed nerve in cross section showing nerve bundle (arrows) and surrounding connective tissues. Unstained bright-field photo. (B) Higher power of circled area shown in panel A. (C) Same section as shown in panel B photographed using epifluorescence light. Circled area contains FG labeled axons. (D) Higher-power fluorescence photo of circled area showing fluorogold (FG)–labeled axons in connective tissues outside of main nerve bundle. Scale bar = 50 μm.
