title: Establishment of five human malignant non-T lymphoid cell lines and mixed lymphocyte-tumor reaction.
abstract: Five human malignant non-T lymphoid cell lines have been established. THP-4 and THP-7 were derived from two children with common type acute lymphoblastic leukemia (ALL), THP-6 and THP-8 from two children with null cell type ALL and THP-9 from a child with malignant lymphoma. THP-4 was positive for cytoplasmic mu, B4, common ALL antigen (CALLA) and Ia-like antigen (Ia), THP-7 positive for B4, CALLA and Ia, THP-8 positive for B4 and Ia, and THP-9 positive for surface mu-lambda, B1, B4, CALLA and Ia. No antigenic determinants for monoclonal antibodies used were detected on THP-6. THP-4, THP-7, THP-8 and THP-9 were able to stimulate allogeneic lymphocytes vigorously. THP-6 without Ia stimulated not only allogeneic lymphocytes, but also autologous ones. THP-7 did not stimulate autologous lymphocytes.
