title: The morphology of cytoplasts and karyoplasts produced by cytochalasin D.
abstract: The denucleation of L cells and human lymphocytes in suspension was carried out by incubation with cytochalasin D25 and 50 microgram/ml and with ultracentrifugation over a discontinuous Ficoll gradient. Ultrastructural examination of the separate layers confirmed the presence of the anucleate cytoplasm (cytoplasts) with intact membrane and the separated nuclei (karyoplasts).
