Figure 4

Nuclei and cell elongation of brain microvascular endothelial cells. Box plots of nuclei and cell elongation dependent on the line width (10, 25, 50, 75 and 100 µm and NP samples) where 0 denotes a round structure and 1 a line. For the statistical analysis 400 nuclei and cells were used for each condition. The statistics included in figure 4 are summarized in Supplementary Tables S4, S5, and *denotes p ≤ 0.05, **denotes p ≤ 0.01, and ***denotes p ≤ 0.001.
