Fig. 8. Expression patterns of different enhancer-trap lines and REPO in the
Drosophila third instar brain. Each row shows the merged and
single channels of the same brain; the inset in each panel is a magnification
of the interhemispheric region. (A-C) The lio1
insertion drives the expression of nuclear ß-galactosidase in four
REPO-positive interhemispheric cells. (D-F) Colocalization of two
REPO-positive cells with nuclear ß-galactosidase driven by the
GAL4-C155 line is shown. (G-I) GAL4-7B does not drive
expression of nuclear ß-galactosidase in REPO-positive cells. Scale bar:
50 µm.
