Abstract
Human hematopoietic cells produce metastasis-inhibitory factor (MIF). MIF exhibits a remarkable metastasis-inhibitory activity on viral diseases and immunopathies, as well as on malignant tumors. The MIF-producing human hematopoietic cells are easily proliferative by in vitro tissue culture and in vivo proliferation using a non-human warm-blooded animal. T cells exhibit a high MIF producibility. Mitogens augment the production of MIF when used as an MIF inducer.
