ABSTRACT
Synergistic effects of B-cell mitogen Staphylococcus bacteria strain Cowan I (Cowan I) plus T-cell activator pokeweed mitogen (PWM) in generating immunoglobulin-secreting cells (ISC) from human peripheral blood mononuclear cells (MNC) were investigated. ISC were assayed by reverse plaque-forming cells uing protein A-coated red blood cells. Low concentrations of PWM plus Cowan I gave superadditive effects on ISI induction, generating 3-20 times as many ISC as optimal amounts of either mitogen alone. The mitogens together and separately showed similar kinetics of ISC; synergy was observed at every day tested. IgM ISC represented 10% of initial MNC from all cell donors tested even if the donors were low responders to either mitogen alone. The numbers of ISC obtained are higher than previous reports and more uniform among donors, making this a superlative method for studies on normal human immunoglobulin secretion.
