Scer\GAL4sim.PS-mediated expression does not lead to any change in the midline cell fate and the normal number of midline glial cell and midline neurones is formed. Scer\GAL4sca-537.4-mediated expression causes ectopic midline glial cells that migrate laterally as well as within the midline. Scer\GAL4en-e16E-mediated expression causes the induction of CNS neurones in many hemineuromeres close to the position of the 'normal' CNS neurones.
