^*Each mouse received simultaneously two sets of 10⁷ fluorescently labeled, antibody-treated T cells. The exact ratio of green and red cells in the initial cell mix was determined by fluorescence microscopy. Brain, spleen, and liver were harvested 5–24 h later and were snap-frozen. The results are given relative to the ratio of red vs. green T cells in various organs of sacrificed mice.
