In Stentor, the changes i n macronuclear morphology which occur during oral differentiation are known to be regulated by a corresponding series of cytoplasmic changes. The present experiments were designed to determine whether these changes are transmitted to the nucleus through the endoplasm or thr

## Abstract This study suggests that membrane perturbations can affect oral morphogenesis in __Stentor__, possibly by a mechanism involving calcium ions. Exposure of regenerating __Stentor__ to micromolar concentrations of the membrane active local anesthetics dibucaine, tetracaine, or procaine gre
To test the hypothesis that the duration of DNA synthesis is an inverse function of nuclear size or DNA content, the S phase was calculated from PLM analysis for pseudodiploid, tetraploid, and octaploid lines of Chinese hamster cells growing as a monolayer or in suspension. S phase times were found
