Model-based Traction Force Microscopy Reveals Differential Tension in Cellular Actin Bundles

Orientation analysis of focal adhesions, stress fibers, and local displacements for U2OS-cells.
(A) Relative angular distribution of FAs and attached SFs (top, n = 1305). (B) Relative angular distribution of local displacements at anchoring points of SFs (middle, n = 1297). (C) Area distribution of mature FAs with (blue) and without attached SFs (green) (bottom,n = 3612). The distributions are based on a data set of 16 U2OS-cells on soft elastic substrates (Young's modulus E = 8.4kPa).
