Abstract
The ability to estimate and analyze the mechanical forces applied by T cells to an underlying substrate is a central tool for understanding this complex interface. One powerful approach to gaining this insight is the use of elastomer micropillar arrays as the cell culture substrate; the magnitude and direction of forces applied by T cells can be derived from images of the pillar tips as they are being deflected.
This resource provides an example image stack and ImageJ/MATLAB code to carry out analysis.
