Focus-forming ability and surface markers of hamster-human malignant lymphoma hybrids.
We have examined the properties of hybrid cells formed by polyethylene glycol-mediated fusion of the GRC+L-73 line of Chinese hamster ovary (CHO) cells with peripheral blood cells from patients with chronic lymphocytic leukemia (CLL) or with bone marrow cells from patients with malignant lymphoma. The results indicate that hybrid cells can be detected by their ability to form "foci" of characteristic morphology in the presence of a monolayer of parental CHO cells and that clones isolated from such foci express aspects of the differentiation status, as detected by immunologic markers, of the human parental cells.
