Table 1. shRNA transduction of FL-CD34+ cells does not grossly affect the colony formation in the methylcellulose assay.

FL-CD34+ cells (2 × 105) were transduced with lentiviral vectors expressing sh1005 or Luc shRNA. Viable cells were quantified, plated (2 × 103 cells/ml), and cultured in humidified chambers for hematopoietic colony-formation using standard methylcellulose medium containing 10 ng/ml of IL-3, 50 ng/ml of SCF, 10 ng/ml of GM-CSF and 3 units/ml of erythropoietin. Cultures were scored at day 14 for granulocyte-macrophage colony (GM), granulocyte, erythroid, macrophage and megakaryocyte (GEMM), and erythroid colony (Erythroid) under the microscope.
