Q-PCR analysis on transduced AML CD34⁺ cells. CD34⁺ cells from AML nos. 2 and 11 were transduced with Venus control vectors or C/EBPα and plated on MS5 for 1 week in the presence of 500 nM 4-OHT, after which GFP⁺ cells were sorted by MoFlo and RNA was extracted for Q-PCRs as indicated. GAPDH expression was used as internal control, and the expression levels were normalized to 1 in the Venus control groups. Error bars denote the standard deviations, belonging to the normalized means as they are shown. ND indicates not detectable, expression was below detection threshold.
