Figure 6.

The preferential outgrowth of neurites from explants of E14 nodose ganglia toward a cocultured explant of distal foregut is blocked by soluble laminin. The difference in neurite density in defined regions of outgrowth either toward the cocultured gut or 180° away from it was calculated. The mean of the differences was used to compare conditions; a mean difference greater than 0 signifies attraction. The selective extension of nodose neurites towards the cocultured foregut is blocked significantly by soluble laminin (p < 0.05). Error bars = standard error of the mean.
