MITOSIS AND GROWTH IN BIOLOGICAL TISSUES

We present a simulation of the growth of a two-dimensional biological cellular system in which the cells experience mitosis whenever the (ar ea)/(perimeter) ratio reaches a critical value. The model also include s the effect of interfacial energy and temperature. A stationary state with a constant average area is attained. We calculate the distributi on of cells as a function of area, perimeter, and number of sides and also the two-cell correlation function. The results depend on temperat ure and are in agreement with experimental data, simulations, and theo retical models.
