Lineage infidelity following exposure of T lymphoblasts (MOLT-3 cells) to
5-azacytidine
LJ Smith and EA McCulloch
The appearance on single leukemic blast cells of markers of at least two
different lineages has been termed lineage infidelity. MOLT-3 cells, a
continuous line of human T lymphoblasts, express T cell markers as defined
immunologically with monoclonal antibodies. Following a single exposure to
5-azacytidine, other markers, usually associated with non-T cell lineages,
appeared transiently. A stable clone with lineage infidelity was obtained
by selection from colonies expressing novel markers. Marker expression
followed reproducible kinetics during growth. 5-Azacytidine-treated MOLT-3
subclones may be useful models in the study of lineage infidelity and gene
expression.
