FIG. 7.

Quantification of cell adhesions in 2D and 3D matrices. Z projections of β₁ staining of human fibroblasts in 2D and 3D matrices were created. The axial ratio (A) of the cell adhesions were compared for each of the 3D and corresponding 2D matrices. The average number of cell adhesions per cell was also compared (B), along with the total area covered by cell adhesions per cell (C). Statistical analyses were performed using analysis of variance and Tukey posttests (n = 8–13 cells). **p < 0.01.
