Contact requirements for suppression of T-cell proliferation by CD14 cells. Responder-derived G-CD14 cells were added directly to MLC or were separated by a 0.45 μm porous polycarbonate membrane (+ membrane). Values for 3H-thymidine incorporation represent the mean cpm ± SEM from sextuplicate cultures with values from autologous background controls subtracted.
