Abstract:	Mouse B lymphocytes were stimulated at high cell concentrations with goat anti-IgM antibodies, which leads to the induction of B cell proliferation without the addition of any growth factors. After 48 hr, blast cells were purified and cultured at low cell concentrations. Proliferation and differentiation of purified B lymphocyte blasts is then dependent on the addition of either mitogens (e.g., LPS) or certain lymphokines derived from activated T cells or macrophages. One such lymphokine was isolated from supernatants of various activated T cells and characterized by gel filtration as a material with an apparent m.w. of 40,000 to 50,000, similar to BCGF II. It supports the proliferation of the B cell blasts and induces their differentiation into plaque-forming cells. Lymphokines such as BCGF I, interleukin 2, and BCDF gamma could neither maintain growth nor induce differentiation of B lymphocytes preactivated by goat anti-IgM.
