Kaplan-Meier plots showing survival of mice that received Tg B-cell lymphoma transplants. Non-Tg mice were irradiated with 6 Gy (dashed line and dotted line) or 8 Gy (solid line) and inoculated subcutaneously with 10⁷ purified B cells from the spleen of a Tg donor with lymphoma (dotted line and solid line) or 10⁷ purified B cells from the spleen of an asymptomatic Tg donor (dashed line). For dashed line, n = 4; for dotted line, n = 6; and for solid line, n = 15. Control indicates B cells from asymptomatic Tg donor; and DLCL, diffuse large B-cell lymphoma.
