Detection of human GFP⁺ cells in mice that received transplants of transduced human fetal liver cells 6 weeks previously.

NOD/SCID mice that received transplants of mock-transduced (top panels) and MSCV-HS2-β-globin-GFP virus-transduced (bottom panels) human fetal liver cells were killed after 6 weeks and the marrow cells analyzed by FACS after staining with antibodies to the different human hematopoietic lineages shown. In this example a high degree of engraftment with human cells was attained in both mice (left panels) and in the recipient of transduced cells, a high proportion of all lineages of human cells produced were GFP⁺.
