Fig. 6. Frequency of wings cultured in vitro without 20E that have 1, 2, 3, 4 or
more A101-positive nuclei in two early born sensilla (GSR and ACV). Grey bars
show the data from discs at the onset of culture, black bars show the data
from discs cultured for 22-24 hours in vitro without 20E. A and C show the
results from discs of early wandering larvae; B and D show discs from
mid-wandering larvae. Frequencies are based on analysis of 19-24 discs.
