Bone marrow cells from indicated donor mice were depleted from B220⁺ and Thy1.2⁺ cells and injected in a 1:1 ratio to a total of 6×10⁶ cells per mouse (excluding group A where 3×10⁶ cells per mouse were injected). Numbers of peritoneal exudate cells of mice are presented 8 to 10 weeks after adoptive transfer (n = 5).
