Responses of BDNF-raised DRG neurons to NGF-coated beads
| Concentration of BDNF (ng/ml) | (n) | % Growth cone turning | % Persistent contacts |
|---|---|---|---|
| 0.05 | 12 | 17 | 90 |
| 10.00 | 10 | 10 | 90 |
| 30.00 | 17 | 24 | 75 |
Concentration of BDNF refers to the concentration the neurons were raised in and that which was also present when NGF-coated beads were introduced to the cultures. Percent persistent contacts refers to the percentage of growth cones that did not turn after contact with an NGF-coated bead but that formed persistent contacts with the beads (see text for the definition of persistent contact).
