Mixed lymphocyte reaction. Results (mean ± SD of 4 independent measurements) of representative mixed lymphocyte reaction experiments with the indicated stimulatory cell numbers per 105 respondent cells. (A) Cells cultured 18 days with (black columns) and without TGF-β (gray columns). 0 indicates no stimulatory cell; and anti-CD3/anti-CD28 (pale gray column), lymphocytes stimulated only with the indicated antibodies. The differences between TGF-β treated and untreated cultures were significant for all cell ratios (P < .05). (B) Cells cultured 18 days with TGF-β (black columns) and with anti–TGF-β (white columns). The differences between TGF-β treated and untreated cultures were significant for both cell ratios (P < .05).
