Figure 5
Mitotic clones around the antennal nerve label with 5'-bromo-2'-deoxyuridine (BrdU). Two mitotic, single cell clones are marked by expression of lacZ in a 3-day-old adult X15-29/X15-33 brain. One of the two β-galactosidase-positive cells also stains for BrdU (white arrow), while the second does not (white arrowhead). The images are a z-series projection of 24 0.3 μm sections. Dorsal is to the upper left. AL, antennal lobe; AN, antennal nerve. The scale bar is 10 μm.
