Abstract:We show that the anterior, prestalk region of the Dictyostelium slug contains cells which express, or have expressed, a prespore-specific marker. We term these cells "prespore-like cells" (PLC). In newly formed slugs there is a sharp prespore/prestalk boundary, with very few PLC, but after several days of migration the clear demarcation between prespore and prestalk zones breaks down because the number of PLC increases dramatically. This is consistent with previous observations showing there to be rapid interchange of cells between the prestalk and prespore regions. This is not, however, their only source, as a scattering of PLC appear when separate prestalk and prespore regions first become apparent at the time of tip formation. Also, at culmination, there is respecification of "prespore" cells at the prestalk/prespore boundary to form part of the mature stalk. The existence of these cells, and of PLC, may explain why we find prespore-specific mRNAs in mature stalk cells.
