Abstract
The elastic interaction between a string of cells and an individualcell on an elastic substrate is investigated numerically using theforce-dipole model. This interaction is found to be of short range, andthe cut-off distance is about 1.4 times of the length of the cell. Theenergy-minimization distance is about half the cellular length. Thespecific relationship between the cellular reorientation and thecellular position are obtained quantitatively. A critical distance isfound, and the cellular orientation has an abrupt change at thistransition point.
