Experimental Protocol


We have established a culture system whereby we retrovirally transduce human CD34+ cells, obtained from cord blood, with the leukemia fusion gene AML1-ETO. Cells expressing this fusion protein are able to proliferate long-term in vitro in a cytokine dependent manner. AML1-ETO-expressing cord blood cells have a large population of primitive self-renewing CD34+ cells with continued abnormal differentiation. We grow these cells in serum-free conditions using the BIT supplement from Stem Cell Technologies. For the current experiments we used cell cultures that had been proliferating in vitro for 8-12 weeks, in a cytokine cocktail of SCF, TPO, FLT3L, IL-6 all at 20 ng/mL and IL-3 at 10 ng/mL. Control cord blood samples that were CD34 purified were expanded for 5-8 weeks in the same culture media as used for AML1-ETO cells. All samples were magnetically selected for the CD34+ population, returned to culture, and one week later again selected for CD34+ cells and then lysed for RNA isolation.
