Stage 12 embryos expressing vnd^Scer\UAS.cCa under the control of Scer\GAL4^sca-537.4 show a reduction in the number of glial cells in the protocerebrum, deutocerebrum and tritocerebrum.

Expression of vnd^Scer\UAS.cCa under the control of Scer\GAL4^69B results in the formation of extra ventral neuroblasts and extra ventral muscle founder cells in the embryo.

Embryos expressing vnd^Scer\UAS.cCa under the control of Scer\GAL4^sca-537.4 show duplications and occasionally triplications of GMC 1-1a-like and GMC 7-1a-like cells. Duplications and triplications of aCC/pCC neurons are seen at later stages. Deletions of RP2 are seen in 16% of hemisegments, while duplications of RP2 are seen in approximately 47% of hemisegments. Embryos expressing vnd^Scer\UAS.cCa under the control of Scer\GAL4^Kr.PM show duplications of U motor neurons. The RP2 neuron is often absent or its position is displaced. aCC/pCC neurons appear to be duplicated.
