Fig. 2.
Directional cell migration within teardrop microchannels. Time-lapse images (in hours) show the movement of (A) NIH3T3 fibroblasts. (B and C) Fluorescence images of NIH3T3 fibroblasts on the 2D teardrop micropatterns. The cells are stained to observe F-actin (green), nucleus (blue) and the Golgi apparatus (red) distribution during migration. Scale bars: 100 μm.
