Dynamics of Spreading and Alignment of Cells Cultured In Vitro on a Grooved Polymer Surface

Figure 6

Time-lapse phase contrast images of rat myoblasts freshly seeded onto a grooved polyester film. The grooves were oriented vertically. Arrows indicate the location of cytoplasmic protrusions. The cell in the upper panel shows 3 major initial cytoplasmic protrusions, while multiple protrusions are visible on the cell in the lower panel. Scale bars, 20 𝜇m.
