Figure 4.

Astrocyte nuclei angle histograms on patterned collagen gels. The angles of observed astrocyte nuclei were compiled into histogram with 10° bins for A) unpatterned collagen control, B) aggrecan stripes, C) fibrinogen stripes, D) fibronectin stripes, and E) laminin stripes. The dotted curves indicate the Gaussian model fit for each data set. These fitted curves were used to calculate the F) mean angle and full-width-half-max (FWHM) for each pattern.
