Figure 6From: Differential knockdown of TGF-β ligands in a three-dimensional co-culture tumor- stromal interaction model of lung cancer 3D co-culture model. Hematoxylin and eosin staining of 3D cultured gels composed of A549 and HFL-1 cells transduced with the indicated miRNAs. Upper panels: HFL-1 cells transduced with NTC miRNA. Lower panels: HFL-1 cells transduced with miRNAs against TGF-β1 and TGF-β2 (TGF-β1 + β2 KD). Invading cells are indicated with arrows. Scale bar: 100 μm.Back to article page
