Mesenchymal Stem Cell-Derived Exosomal miRNA-222-3p Increases Th1/Th2 Ratio and Promotes Apoptosis of Acute Myeloid Leukemia Cells

<div>Overexpression of BM-MSC exosomal miR-222-3p promotes Th1/Th2 ratio and caspase 3 expression <i>in vivo</i>. (a) Flow cytometry analysis was performed to analyze the Th1/Th2 ratio <i>in vivo</i> in the control group, the AML group, the Nor-exosome + AML group, and the Aml-exosome + AML group, the Nor-exosome + mimic NC + AML group, the Nor-exosome + miR-222-3p mimic + AML group, the Nor-exosome + inhibitor NC + AML group, and the Nor-exosome + miR-222-3p inhibitor + AML group. (b and c) The mRNA and protein expression of IRF2 and caspase 3 expression in the above eight groups were measured by western blot and RT-qPCR, respectively. *<span class="nowrap"><svg
