Neurite lengths in the presence of anti-α₆Ex and anti-α₃Ex1. Representative cultures from the experiments in Figure 6 were examined for effects of integrin-specific antibodies on neurite length. Processes longer than 1 cell body diameter were measured as described in Materials and Methods. Values represent mean neurite length ± SD (on laminin) or ± range (on merosin), normalized to mean length under control conditions.nindicates the number of processes measured for each condition.Statistical significance was determined using Dunnett’s test for multiple comparisons against a single control, performed using normalized data.
