Total CGRP release (AUC) per mm neurite length.

(A) Values for the individual compartments following neurite stimulation (filled symbols) and soma stimulation (open symbols). Symbols indicate the added growth factors in the chambers; N-N-N denotes NGF in the lateral and central compartments (circles); G-N-G denotes GDNF in the lateral compartments and NGF in the central compartment (squares); Ø-G-Ø denotes no growth factor in the lateral compartments and GDNF in the central compartment (triangles). Data derived from the experiments presented in Fig 4. (B) Mean values from data presented in A. Error bars indicate ± SEM; asterisks indicate p<0.05.
