Y-shaped in vitro assay for axonal segregation. (A) Gelfoam-diffusion delivery of neurotrophins into the distal arms was used to differentially entice axonal outgrowth from neonatal DRGs. Bottom: higher magnification shows axonal growth from the DRG (arrow) in the choice area. (B) Diffusion of green (Cy3) and red (Cy3) labeled antibodies, were imaged over time and quantified to demonstrate independent gradient formation.
