Df(3R)lb/Df(3R)e-F1 are uncovered for lbl, lbe and bap. In these embryos no dramatic change is seen in the ventral nerve cord morphology. However, there seem to be slightly more lateral projections compared to wild-type. The glial cell population is also affected in its positioning and number. An increased number of medially located glial cells is seen, as is a partial loss or abnormal positioning of lateral exit and subperineural glial cells. An additional ~2.3 glial cells are seen per hemineuromere. Defects are also seen i the segmental nerves. The distance between the ISN and SN bundles is much more variable and larger than seen in wild-type.
