Figure 1. The respiratory epithelia provide the largest reservoir of hemocytes in adult Drosophila.

Figure 1.

(A-C) Cryosections of adult Drosophila, HmlΔ-DsRednls hemocytes red, phalloidin green, respiratory epithelia (air sacs) blue. (A) Longitudinal section, anterior up; (B) cross section of head, dorsal up; (C) cross section of thorax, dorsal up. (D) Adult Drosophila, genotype HmlΔ-DsRed/+; btl-GAL4, UAS-GFP/+ ; hemocytes red, tracheal marker green; respiratory epithelia (air sacs) blue; dissection of head, anterior up; size bar 250μm. (E) Schematics of the the tracheal system and respiratory epithelia of the thorax and head (blue), hemocytes in red. Dashed lines indicate sections and dissected area shown in A-D. Note that model omits heart area, which is not visible in longitudinal section in (A). For full model, see Suppl. Fig. 1.
