title: Establishment and characterization of Ph1-positive and Ph1-negative lymphoblastoid cell lines from a patient with chronic myelogenous leukemia.
abstract: Two continuously growing in vito cell lines, PB-1049 and LN-1049, were established from a patient with Ph1-positive chronic myelogenous leukemia in extramedullary blastic crisis. PB-1049 was established from Epstein-Barr virus (EBV)-infected peripheral lymphocytes of the patient and had a 46,XY,t(9;22) karyotype. This cell line was shown to be tumorigenic in nude mice, and cultured cells recovered from the tumor nodule showed a 46,XY,6p+,t(9;22) stem line karyotype. LN-1049 was derived from a lymph node culture of the same patient, and was found to be non-tumorigenic in nude mice and karyotypically normal. Immunological examinations on EBV-induced antigens, surface and cytoplasmic immunoglobulin, and monoclonal antibodies, and some enzymatic and electron microscopic studies revealed that both cell lines had attained differentiation into late-B cell stage.
