Figure 3. Hypoxic environment and/or reducing agent improve the transduction efficiency and viability of human Fanconi bone marrow progenitors.
Human Fanconi bone marrow mononuclear cells were transduced overnight with the GFP vector at a vector to cell ratio of 10:1 and plated in colony assays at 20,000 cells per plate. During the transduction and colony assays, cells were exposed to either 21% or 5% O2 with or without 1mM NAC, a reducing agent. Transduction efficiency increased from 16.7% to 47.8% by reducing oxygen from 21% to 5% and adding 1 mM NAC.
