A water soluble extract from the bark of the Samoan medicinal plantAlphitonia zizyphoides A. Gray (Rhamnaceae), enhances the plating efficiencyin vitro of lymphoid cell lines as well as the survival of bone marrow cells and normal T and B lymphocytes. Furthermore, the inclusion of bark-extract into culture media enhances the cloning efficiency of a T-hybridoma cell line by more than 30 times at otherwise unsuitably low serum concentrations, but does not completely substitute for serum.

The stromal cell line S17 supports the growth of lipopolysaccharide‐stimulated CBA/N spleen cell colonies in vitro
Evidence is shown that the colony‐forming ability of CBA/N spleen cells can be effectively restored by the bone marrow stromalderived cell line S17, and the direct involvement of S17 in this process is indicated.
A stable TCGF-producing T cell hybridoma and its thioguanine-resistant variant suitable as a tool for the construction of new functional T hybridomas.
As most convincingly demonstrated with cloned helper T cells, TCGF production is the result of specific antigen recognition by the T cells in the context of histocompatibility antigens presented by viable adherent, macrophage-like cells.
Identification of a T cell-derived b cell growth factor distinct from interleukin 2
A factor found in induced supernatants of the mouse thymoma EL4 that co-stimulates with anti-IgM antibodies in short-term cultures of purified B lymphocytes to induce polyclonal B cell proliferation but not antibody-forming cell production is reported.
Conditions controlling the proliferation of haemopoietic stem cells in vitro
A liquid culture system is described whereby proliferation of haemopoietic stem cells (CFU‐S), production of granulocyte precursor cells (CFU‐C), and extensive granulopoiesis can be maintained in
Partial purification and characterization of a BCGFII from EL4 culture supernatants.
It is shown that a very similar BCGFII activity can be obtained from EL4 culture supernatants induced by PMA, which can be detected in 18 to 24 hr by virtue of its ability to cause in vitro proliferation of in vivo BCL1 tumor B cells.
Continuous cultures of fused cells secreting antibody of predefined specificity
The derivation of a number of tissue culture cell lines which secrete anti-sheep red blood cell (SRBC) antibodies is described here, made by fusion of a mouse myeloma and mouse spleen cells from an immunised donor.
Enforced BCL2 expression in B-lymphoid cells prolongs antibody responses and elicits autoimmune disease.
E mu-bcl-2-22 mice constitute a transgenic model for a systemic autoimmune disease resembling the human disorder systemic lupus erythematosus, and most mice spontaneously produced antibodies to nuclear antigens, and 60% developed kidney disease, diagnosed as immune complex glomerulonephritis.
