Stable gene expression levels in peripheral blood cell subsets of dogs. Animals were treated with lentivector-transduced GFP/YFP-expressing CD34-enriched cells in an autologous transplantation setting. (A) G206; (B) G236; (C) G293. x axis, days posttransplantation (DPT); y axis, relative percentage of G/YFP-expressing cells. Solid lines, GFP marking; dashed lines, YFP marking; squares, lymphocytes; triangles, granulocytes.
