Figure 2. Alignment and migration of mouse corneal epithelial cells on grooved quartz substrata. A: Images of aligned (left and middle) and non-aligned (right) primary mouse corneal epithelial cells on 2 μm grooved quartz surfaces. Yellow lines indicate the long axis of the cells. See Table 1 for quantification. B: Tracks of cells migrating on 2 μm quartz grooves. Scale bar represents 50 μm.
