CD11b expression is increased in HOXA5-transduced cultures. (A) In 6 of a total of 6 experiments in which MC192⁺CD34⁺ cells were cultured in erythroid conditions (P = .03 by Wilcoxon Rank test) and (B) 6 of 9 experiments cultured in myeloid conditions, HOXA5increased the frequency of cells expressing CD11b (P = .009).
