Antitumor activity of T lymphocytes to cervical and lung tumors in NOD/SCID mice with and without previously injected cord blood. A, representative tumors size and weight at 8 weeks after injection with A549 (2 × 106 cells) into mice with or without previous cord blood transfer were shown (* P <0.05). B and C, The size and weight of tumors were measured 8 weeks after subcutaneous injection of Caski (B) or HeLa (C) cervical cancer cells without and with CB T-cell grafts (* P <0.05). D, phenotype of cells from splenocytes of mice with T-cell grafts followed by injections with Caski cells; flow cytometry analysis with antibodies to CD3, CD45RO, and CD45RA.
