Figure S2. Expression of vimentin (a) and MT1-MMP (b) in invadopodia of PANC-1 TSs. In-well staining was carried out for vimentin and MT1-MMP (green), F-actin (red) and DAPI (blue) in whole TSs. Optical sections were acquired at 0.5 μm intervals and stacked into a z-projection. Scale bars: 20 μm. (TIF 1254 kb)
