Fig. 6. dronc mutant embryos contain additional cells. (A,C,E) Wild-type embryos stained for the midline glia (A), Krüppel (C), and Elav (E). (B,D,F) Maternally and zygotically dronc^I29 mutant embryos stained for midline glia (B), Krüppel (D) and Elav (F). Similar results were obtained for dronc^I24 embryos (data not shown). (C,D) Ventral views of the CNS. Note the enlarged band in D compared with C (white bar). The numbers in E and F indicate the number of chordotonal cells in each cluster.
