Evidence for cell surface control of macronuclear DNA synthesis in Stentor.
In cell grafts, Stentor macronuclei associated with separate regions of cell surface can be made asynchronous with regard to morphology and DNA synthesis even though they demonstrably share a common endoplasm. These results suggest a mechanism for nuclear differentiation within a single cytoplasmic compartment, based on cell surface differences.
