Abstract

Nuclear-cytoplasmic interactions have been studied in mammalian cells through the formation of cybrids (cytoplasts fused to whole cells) using a mutation for cytoplasmically inherited chloramphenicol resistance (CAPΓ) (Bunn et al., 1974; Wallace et al., 1975; Wallace and Eisenstadt, 1979). McBurney and Strutt (1979) fused karyoplasts to whole cells, a product they termed karyobrids. However, their isolation technique did not distinguish nuclear hybrids from whole-cell hybrids. Muggleton-Harris and Palumbo (1979) produced nuclear hybrids, identified on the basis of nuclear morphology. Because both of these procedures lacked genetic verification, we have developed genetic and physical-genetic techniques for isolating nuclear hybrids. These techniques permit the isolation and verification of nuclear hybrids with the cytoplasmic and mitochondrial content of predominantely one cell.
