Additional file 3: Figure S2. of Functional integration of the circulatory, immune, and respiratory systems in mosquito larvae: pathogen killing in the hemocyte-rich tracheal tufts LeagueGarrett HillyerJuliån 2016 The sessile hemocytes of adults preferentially bind thin trachea. (A, B) Bright-field overlay (A) and fluorescence (B) images showing hemocytes (CM-DiI; red) bound to thin abdominal trachea. (C, D) Bright-field overlay (C) and fluorescence (D) images showing very few hemocytes bound to the large trachea of the eighth abdominal segment, which lacks tracheal tufts.
