(B) Representative confocal imaging of NimB4-sGFP macrophages of embryo at stage 16; lateral (left) and ventral (right) views; Tissues were stained with anti-GFP (green, corresponding to NimB4-sGFP) and anti-SIMU antibodies (red, corresponding to macrophages). The arrows show the presence of NimB4-sGFP inside the embryonic macrophages. Scale bars = 20 μm
