In this article (), which was published in the July 2011 issue of Cancer Discovery (1), the name and affiliation of the eighth author is incorrect. The correct name and affiliation are Tan A. Ince, Department of Pathology, Braman Family Breast Cancer Institute and Interdisciplinary Stem Cell Institute, University of Miami Miller School of Medicine, Miami, Florida.
In addition, there are several textual errors in the Results and Methods sections. These changes do not affect any of the data presented in the manuscript or the conclusions. The applicable passages including the correct reference callouts are provided below:
Results, page 152, Figure 6 legend, 4th sentence:
The strain energy was calculated as the product of measured bead displacement and reconstructed traction stresses, integrated over the cell footprint.
Methods, page 155, second column, first paragraph:
We used Student t test to calculate statistical significance.
Methods, page 156, first column, first paragraph:
The regularization parameter λ2 = 10−6 has been determined using the L-curve method.
Methods, page 156, first column, first paragraph:
Traction forces were reconstructed from the measured bead displacements using an implementation of the regularized Fourier Transform Traction Cytometry method (37) provided in Ref. 17.
Methods, page 156, first column, second paragraph:
Here, 
and 
denote the reconstructed traction stress and measured bead displacement, respectively.
Methods, page 156, first column, second paragraph:
We used Student t test to calculate statistical significance.
