GFP⁺ cord blood cells after transduction with the MSCV-HS2-β-globin-GFP virus.

FACS dot plot of cells harvested 2 days after transduction and stained with antihuman CD34-Cy5. The left panel shows results for mock-transduced unstained cord blood cells and the right panel for the test cells. In this example 39% of all cells and 35% of the CD34⁺ cells were GFP⁺.
