Similar rearrangements of T-cell receptor beta gene in cell lines and uncultured cells from patients with large granular lymphocyte leukemia.
We established interleukin-2-(IL-2) dependent cell lines from three patients with large granular lymphocyte (LGL) leukemia. Phenotypic analysis demonstrated retention of the CD3+, CD8+ phenotype that was observed in the original leukemic LGL. Unique rearrangements of T-cell receptor beta gene occurring in uncultured leukemic LGL, were also found in cell lines, which suggests that the cell lines were derived from the original leukemic LGL clone in each case.
