Fig. 3. DNA fragmentation in vCrz neurons. Wild-type prepupal CNSs at 2
hours APF (A) or 3 hours APF (B) were subjected to TUNEL assay
(right), followed by Crz immunohistochemistry (left). These images were merged
to show superimposition of the two signals (center). TUNEL-positive vCrz
neurons are indicated by arrows and TUNEL signals in non-vCrz cells by
arrowheads. Scale bar: 10 µm.
