  1. Embryonic E16 hippocampal cultures were prepared as described (11,17). Twenty-four hr after plating, cells were fixed and stained with a tubulin antibody and their morphology analyzed in 20 fields from three different experiments.
  2. Values are given as percent of total. Each number represents the mean ± SEM. *Differs from wild-type P < 0.001.
