Abstract:The effect of various concentrations of rat-liver macrophages on the Con-A-induced blastogenesis of syngeneic spleen lymphocytes has been studied by means of flow-cytometric methods and by measurement of the uptake of 3H-thymidine. By measuring the distributions of cellular and nuclear volume and cellular DNA to characterize the progression of responding lymphocytes through the cell cycle, we have distinguished a promotive and an inhibitory effect of macrophages. The promotive effect is on the number of cells … Show more
