title: Evidence for cell surface control of macronuclear DNA synthesis in Stentor.
abstract: 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.
