KIT and leukemia: In our previous work, we had already shown that results obtained with Kit-pretreated (DC/DCleu-containing cells) as stimulator cells in the MLC were comparable with those obtained after LAA stimulation: no increased frequencies of leukemia-specific cells were seen [8], pointing (again) to the stimulatory (DC/DCleu-inducing) effect of Kit M, leading to increased production of leukemia-specific cells after MLC (without additional LAA stimulation).
