Image shows adult human fibroblast cells with intracellular proteins involved in adhesion of these cells to an extracellular matrix. Magenta represents actin stress fibers in a cell and green staining represents a focal adhesion protein vinculin, which together contribute to how strongly these cells adhere to a matrix surface. Blue is the nucleus of a cell.
