GH146-glia does not originate from the sensory lineages. (A) Third antennal segment from 36 hr APF wildtype pupae stained with anti-Repo showing the position of glial cells. (B) 36 hr APF ato1/Df(3R)p13antenna shows a significant reduction of glial cells, compared to the wildtype. (C) GH146::GFP was crossed into ato1/Df(3R)p13to visualize GH146-glia in the late pupa. (D) 36 hrs APF lz3 antenna stained with anti-Repo. (E). lz3; GH146::GFP antenna stained with anti-GFP. (F) Antenna in (E) was also stained with mAb22C10. Sensory neurons are markedly reduced in number. Ar-arista. Numbers in panels A,B and D represent the mean and standard deviation of glial cell number in at least 8 antenna. For E only 5 antennae were counted.
