Chemotactic cell sorting in Dictyostelium discoideum.

چکیده
We made mixed mounds of vitally stained prestalk cells and unstained prespore cells, from Dictyostelium discoideum (Dd), and exposed these to external 3',5'-cyclic-AMP (c-AMP) sources. We show that prestalk cells will sort out by moving directionally toward c-AMP sources held at less than 10(-5) M c-AMP. This is evidence for cell sorting via chemotaxis. We present arguments that the natural cell sorting, observed during Dd development, is also chemotactic to c-AMP.

Modelling cell movement, cell differentiation, cell sorting and proportion regulation in Dictyostelium discoideum aggregations.
Understanding the mechanisms that control tissue morphogenesis and homeostasis is a central goal not only in developmental biology but also has great relevance for our understanding of various diseases, including cancer. A model organism that is widely used to study the control of tissue morphogenesis and proportioning is the Dictyostelium discoideum. While there are mathematical models describ...
متن کاملNavigating signaling networks: chemotaxis in Dictyostelium discoideum.
Studies of chemotaxis in the social amoeba Dictyostelium discoideum have revealed numerous conserved signaling networks that are activated by chemoattractants. In the presence of a uniformly distributed stimulus, these pathways are transiently activated, but in a gradient they are activated persistently and can be localized to either the front or the back of the cell. Recent studies have begun ...
متن کاملCell sorting out during the differentiation of mixtures of metabolically distinct populations of Dictyostelium discoideum.
The behaviour, during the multicellular phase of the life-cycle, of amoebae of Dictyostelium discoideum grown indifferent media is described. Amoebal populations were marked by growthtemperature-sensitive genetic lesions which do not interfere with developmental phenomena. The fate of cell populations was determined by measuring the relative number of mutant and wild-type cells at various stage...
متن کاملDictyostelium discoideum: cellular self-organization in an excitable biological medium.
The dynamics which govern the establishment of pattern and form in multicellular organisms remain a key problem of developmental biology. We study this question in the case of morphogenesis during aggregation of the slime mould Dictyostelium discoideum. Here detailed experimental information allows the formulation of a mechanistic model in which the central element is the coupling of the previo...
متن کاملAnalysis of chemotaxis in Dictyostelium.
Dictyostelium discoideum is an excellent model organism for the study of directed cell migration, since Dictyostelium cells show robust chemotactic responses to the chemoattractant cAMP. Many powerful experimental tools are applicable, including forward and reverse genetics, biochemistry, microscopy, and proteomics. Recent studies have demonstrated that many components involved in chemotaxis ar...
