Fig. 3. pea3 and erm knockdown affects morphogenetic capacity of MMT cells. si pea3 1-2, si erm 1-2 and si ctrl transfected MMT cells were seeded at low density on a Matrigel. 3D cultures were treated with HGF/SF (20 ng/ml). After 7 days, cells were stained with Neutral Red and fixed. Whole-mount pictures were taken at 50x (A) or 100x (B) using a microscope. Scale bars, 100 µm (A) or 100X (B). Images are representative of three experiments performed in duplicate.
