Figure 4From: Topographical control of cell-cell interaction in C6 glioma by nanodot arraysTopographic effects on the density of branching points and meshes. (a) The density of branching is plotted against the diameter of the nanodots and grouped by incubation time. (b) The density of the meshes is plotted against the diameter of the nanodots and grouped by incubation time. The values are expressed as the mean ± SD calculated from at least six experiments. *p < 0.05, **p < 0.01.Back to article page
