| Abstract: | A high calcium concentration is known to induce stalk differentiation of the cellular slime mold D. discoideum. Therefore, the change in the calcium content of this organism during differentiation was studied and found to vary during development, more calcium being found in the anterior prestalk cells of the pseudoplasmodium (slug) than in the posterior prespore cells. It is concluded from the results that calcium is of importance in the cell differentiation of this organism and particularly in stalk formation. |
