  • Patent number: 8216837
    Abstract: A method of producing lymphocytes characterized by comprising the step of culturing lymphocytes in the presence of a modified recombinant fibronectin fragment which has overlapping parts of the heparin-binding domain of fibronectin. This method makes it possible to achieve a high cell proliferation rate. The lymphocytes obtained thereby are appropriately usable in, for example, adoptive immunotherapy and, therefore, expected as highly useful in the clinical field. Moreover, a novel modified recombinant fibronectin fragment is provided.
