Src inhibition rescues invasion but not formation of invadopodia-like protrusions in mlt.

(A–C) Lateral views of live 5 dpf WT (A) and mlt (B, C) larvae. Treatment with the Src-I1 inhibitor rescues invasion in mlt (C). The size of the intestinal epithelium in the treated mlt larva (C) is reduced compared with the untreated mlt larva (B). (D–G) Histological cross-sections of 4 dpf WT (D) and mlt (E–G) Tg(miR194:Lifeact-GFP) larvae immunostained with antibodies against laminin (red) and GFP (green). Nuclei stained blue with DAPI. Arrows point to invadopodia-like protrusions arising from the basal epithelial cell membrane of Src-I1 treated mlt larvae (F, G). Pronounced invasion with distortion of intestinal architecture is evident in the untreated mlt larva (E). Note that invasion is markedly reduced in the Src-I1 treated mlt larvae despite the presence of the invadopodia-like protrusions (white arrows in F, G).
