Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa. It is one of a number of distantly related spore-forming species collectively referred to as the slime molds, due to the presence of both single-celled and multicellular forms at different stages in its life cycle. D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular "slug" and then into a fruiting body within its lifetime. Its unique asexual life cycle consists of four stages: vegetative, aggregation, migration, and culmination. The life cycle of D. discoideum is relatively short, which allows for timely viewing of all stages. The cells involved in the life cycle undergo movement, chemical signaling, and development, which are applicable to human cancer research. The simplicity of its life cycle makes D. discoideum a valuable model organism to study genetic, cellular, and biochemical processes in other organisms.
