[Electrophoretic mobility in acute null cell lymphoblastic leukemia].
The electrophoretic mobility (E.M.) (evaluated by cytopherometer) of human normal lymphocytes, shows a group of cells with a fast mobility, identifiable as T lymphocytes, and a second group with a slow mobility which can be characterized as B lymphocytes. Six cases of Acute Lymphoblastic Leukaemia characterized by negativity of immunological markers and classified as "Null Cells", and ten cases of B cell Chronic Lymphocytic Leukaemia were studied in order to investigate the E.M. behaviour of leukaemic cells and so a comparison with T and B normal lymphocytes migration. The blasts of Acute Lymphoblastic Leukaemia show a E.M. nearly similar to the fast group of normal lymphocytes, while lymphocytes of the B cell Chronic Lymphocytic Leukaemia migrate as the slow component of normal lymphocytes. The possibility of the utilization of cell E.M. in addition to immunological and cytochemical data, into the characterization of Acute Leukaemias is suggested.
