Abstract excerpt
In Dictyostelium development, prestalk cells first differentiate at scattered positions in the aggregate and then sort out, probably by chemotaxis to cAMP. They may regulate their proportions by selective depletion of the stalk cell inducer, DIF-1. Once sorted, prestalk cells form a DIF-1 sink, which can produce gradients of DIF-1 and its metabolites in the slug. Global movements of cells in the slug may be...
