Abstract

Human spleen cells were fractionated by percoll density gradient centrifugation and by sorting in the FACS with mixtures of fluorescent antibodies against T cells, B cells, monocytes, and Sig-bearing cells. Cells responsible for powerful MLR stimulation were class II HLA antigen-positive and were concentrated in prepararations depleted of all the markers listed above. These cells represented 1-2% of the initial spleen cells. They were remarkably more active than other HLA class II antigen-positive cells. The procedure described allows rapid enrichment for the responsible cells. It should be useful for further characterization of these cells and for performing studies on their function.
