title: The force of detachment of endothelial cells from different solid surfaces.
abstract: With the use of a technique based on the detachment of single cells by suctioning of the cells with a glass micropipette, the authors studied human endothelial cell adhesion on 4 different surfaces (Fluorocarbon FC 721, polyester, nylon, glass) versus time of contact in phosphate buffered solution and a complete culture medium. It was observed that the force of detachment from solid surfaces of endothelial cells increases significantly with time and with increasing substrate surface tension in PBS and decreasing substrate surface tension in complete culture medium. This dependence of cell-fiber interactions with surface tension of the fibers demonstrates that cell adhesion in the authors' experimental conditions in primarily controlled by surface tension.
