        exdB108 mutant embryos show an increase in the number of NB6-4a progeny. Some of these cells migrate medially in a pattern similar to glial cells of NB6-4t, while others migrate to the dorso-lateral cortex expressin only eg, suggesting neuronal identity.

        (Kannan et al., 2010)

        Mutant embryos lack oenocyte clusters.

        (Brodu et al., 2002)

        Embryos lack both maternal and zygotic exd.
