Abstract

The in vivo distribution of intravenously injected lymphokine activated killer (LAK) cells, generated in vitro with rIL-2 from normal murine splenocytes, was studied in BALB/c mice and compared with that of normal splenocytes. Both normal splenocytes and LAK cells were labeled with 51Cr, and the results were analyzed at 6, 24, and 48 hours after injection by localization index as the parameter. After injection through tail veins of mice, LAK cells were found to migrate to the spleen, lungs, liver, lymph nodes, bones and the kidneys. The apparent increased distribution pattern of LAK cells to the lung at 6 and 24 hours after injection was not detected when normal splenocytes were injected. Since almost one third of the injected LAK cells were found to localize in the spleen, it was postulated that splenectomy would affect the in vivo organ distribution of LAK cells. Accordingly, the in vivo distribution of LAK cells in splenectomized mice was further investigated. Results indicated that splenectomy enhanced the convergence of LAK cells to the lungs, liver, lymph nodes and bones. Therefore, splenectomy may augment the therapeutic effect of the adoptive transfer of LAK cells in pulmonary, hepatic, lymph node and bony metastases.
