Abstract The effects of migration and culmination on patterning of presumptive (prespore and prestalk) cells and mature (spore and stalk) cells of D. discoideum were investigated. The ratio of prespore to total cells, as determined by staining with fluorescein-conjugated antispore globulin, was constant (77%) up until 8 h of slug migration, but then decreased to a level (64%) which thereafter remained unchanged during migration. Cells which lost prespore antigen during migration were located in the posterior (prespore) part next to the agar surface. Upon induction of culmination, however, the ratio of prespore cells quickly increased to the normal level (77%) within 1–2 h. During the transition between migration and culmination prestalk and prespore cells were considerably intermixed within the cell mass, before the normal prestalk-prespore pattern was reestablished at the preculmination (Mexican hat) stage. Spore: stalk ratios within fruiting bodies were normal irrespective of the lengths of slug migration.
