Abstract

Two E‐rosette (spontaneous rosette with sheep red blood cells)‐forming lymphoid cell lines were established. One (HPB‐ALL) was derived from a young male Japanese patient with acute lympho‐blastic leukemia (ALL), and the other (HPB‐MLT) was from a 62‐year‐old female Japanese patient with a leukemic T‐lymphoid malignancy. Formation of E rosettes, absence of any immunoglobulin determinants, absence of EBNA (Epstein‐Barr virus associated nuclear antigen) and very limited stimulating ability in mixed lymphocyte culture, were characteristics mostly identical with those of so far established T‐cell‐derived lymphoid cell lines, MOLT, CCRF‐CEM, CCRF‐HS‐B2, RPMI‐8402 and JM. Only HPB‐MLT, however, has been derived from an aged patient with T‐lymphoid malignancy.

## Abstract Long‐term lymphoid cell lines (LTL) cultured under normal conditions use methionine primarily for protein synthesis, although a significant proportion is converted to S‐adenosylmethionine (SAM) and used for synthesis of the polyamines, spermidine, and spermine. When LTL are cultured und

Lymphoblasts from patients with acute lymphatic leukemia were examined for the presence of surface markers and for their capacity to stimulate allogeneic donors in MLC. Lymphob,!asts from eight patients, which made E rosettes, consistently failed to stimulate allogeneic donors on at least three sepa
