The effect of graded concentrations of MENK on the differentiation of BM-derived DC progenitors in vitro. BM-derived DC progenitors were cultured for 7 days with MENK at range of concentrations (10⁻⁸–10⁻¹⁴ mol/L) and phenotypes of BM-derived DCs were analyzed by FCM. a Immunophenotypes were characterized by FCM. Similar results were obtained from four separate experiments. b The results were summarized in the curve. **p < 0.01 versus in the RPIM 1640 group
