Summary of in vivo gene marking.

Level of peripheral blood mononuclear cell and granulocyteneo gene marking as assessed by semiquantitative PCR at certain time points after transplantation, shown on a logarithmic scale. In each animal black bars (▪) represent the marking level originating from G-CSF+SCF–mobilized target cells; white bars (■), G-CSF–mobilized target cells; and gray bars (░), G-CSF+Flt3-L–mobilized cells.
