      The number of exit glial cell in mutant embryos is higher than in wild-type embryos.

      (Nelson and Laughon, 1994)

      ac protein distribution in Dl9Q embryos show ac expression is not restricted to a single cell of an ectodermal cell cluster, instead most cells of the cluster retain ac expression at a high level, enlarge, delaminate and become neuroblasts.
