To investigate the effect of GAS2DN on CD34+ cells from CML patients, GAS2DN was delivered with concentrated lentivirus, and then either YFP+ or CD34+YFP+ cells were purified with FACS and used for further cellular and molecular analysis (Figure 5A, Figure S4 in File S1). The gene discussed is CD34; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
