Expression of ▵LNGFR in the BM of a mouse 2 months after transplantation of SFCM-transduced (right) and GATA-SFCM–transduced (left) BM cells. Cells were stained with FITC-conjugated anti-▵LNGFR (X axis) and PE-conjugated anti-Sca1, TER 119, and Gr-1 (Y axis) antibodies. Positivity to Sca1 and TER 119 was analyzed in the blast/lymphocyte-gated cells, and positivity to GR-1 was analyzed in the granulocyte-gated cells.
