results obtained from the mouse thymocyte costimulation assay for il-1 , the hybridoma growth factor assay for interleukin 6 ( il-6 ) , the ability to stimulate hpp-cfc , and the ability to block this stimulation with an antibody to murine il-1 alpha suggest that the synergistic activity in af1-19t-cm is probably a mixture of il-1 activity and il-6 or an il-6-like activity .
