Establishment in continuous culture of a T-lymphoid cell line (HD-Mar) from a patient with Hodgkin's lymphoma.

A new cell line, HD-Mar, was established from a pleural effusion of a patient with Hodgkin's lymphoma. Formation of E rosettes, sensitivity to anti-T serum, elevated terminal deoxynucleotidyl transferase activity, presence of T-cell and the common ALL membrane antigens, morphology, and cytochemical staining indicate that the HD-Mar line is of thymic derivation. Absence of any immunoglobulin determinants, the lack of EBNA or any other EBV-associated antigen or function are also characteristics associated with established T- cell-derived lymphoma cell lines. Karyotype analysis indicated a tetraploid origin of the cell line.
