A mathematical model for cell sorting and migration in the slug stage of cellular slime molds <I>Dictyostelium discoideum</I> is proposed. Assuming that a slug is a "mixed fluid" of prespore and prestalk cells, a set of equations which describe the dynamics of cell distribution, internal pressure and velocity of the slug are derived from the balance formula of individual cell movement. These equations are analyzed to obtain the stationary distribution pattern of cells, migration velocity and body shape. The existence of critical size of a slug is predicted.
