Multilineage reconstitution with genetically modified cells. The percentage of GFP-positive cells in immunophenotypically defined cell populations was determined by FACS. The top row shows the profiles of red cells (RBCs) and platelets (PLTs) as defined by forward and side scatter. The percentages of GFP-positive granulocytes (CD11b), monocytes (CD14), T lymphocytes (CD3), B lymphocytes (CD20), and natural killer cells (CD16) are shown in the other panels for animal CJ5B on day 198 following infusion of autologous, transduced CD34⁺ cells.
