## Abstract Human lymphoid cell lines which had been classified on the basis of studies on clonality and morphological, chromosomal and functional parameters as lymphoblastoid cell lines (LCL) of presumed non‐neoplastic origin and Burkitt lymphoma (BL) lines of proven malignant origin, were tested

Abstract
The sister chromatid exchange (SCE) rates of cell lines derived from patients with different malignant and premalignant diseases were studied before and after intracerebral inoculation into nude mice and were compared to the SCE frequencies of cell lines from healthy controls. Lymphoma lines characterized by chromosomal markers as well as chromosomally normal lymphoblastoid cell lines were used. The SCE frequencies of nude mouse tumor‐derived cell lines did not show a homogeneous pattern. They were either as high as, or higher or lower than, the SCE levels of the original cell line. But all cell lines, karyotypically abnormal as well as normal, originating from patients with malignant and premalignant diseases, showed significantly higher SCE rates than the control lines from healthy donors.
