The TCF binding sites are required for expression of the Tig and minR reporters in embryonic hemocytes.

(A–I) Confocal images of stage 15 embryos containing wild-type minR reporter (A–C) and the Hm (D–F) or Wm (G–I) mutants, with immunofluorescence detection of LacZ (green) and MDP-1 (red). Expression of the reporter is greatly reduced when either motif is mutated.
