[Synopsis] The effects of heavy metal ions on the EDTA-sensitive cell contacts, which exist from growthphase stage of Dictyostelium discoideum, was investigated. EDTA-sensitive cell contacts of cells at the growth-phase stage were analyzed in the presence of heavy metal ions. Heavy metal ions Hg^<2+>, Cd^<2+> and Cu^<2+> inhibited EDTA-sensitive cell contacts at concentrations higher than 10^<-5>M, whereas Pb^<2+> did not show any recognizable effects at the same concentration range. The possible mechanisms of action of these metal ions are discussed.
