Abstract (original English)
Background Acute myeloid leukemia (AML) is a highly heterogeneous disease with poor therapeutic outcomes and overall prognosis, particularly in c-Mpl+ AML. c-Mpl , a proto-oncogene, is expressed at significantly higher levels in AML compared to normal human tissue cells. This study aimed to develop a type of targeted exosomes (Exos) capable of delivering anticancer drugs directly to c-Mpl+ AML cells. Methods Human umbilical cord mesenchymal stem cells (hUCMSCs) were isolated as the source of Exos. Fusion CD63 proteins with varying numbers of thrombopoietin (TPO)-mimic peptides, designed to target c-Mpl, were bioengineered to be expressed on the membranes of hUCMSCs and their derived Exos. The targeting capability of the fusion proteins was assessed using the DUAL membrane system, fluorescence resonance energy transfer efficiency, and endocytosis assays. After encapsulating the anticancer drug daunorubicin (DNR), these targeted Exos were evaluated for their ability to eliminate c-Mpl+ AML cells. Safety and efficacy were further tested in a mouse AML model. Results Our findings showed that the engineered hUCMSCs-derived Exos demonstrated excellent targeting ability to c-Mpl and a strong propensity for endocytic uptake by c-Mpl+ AML cells. Among the engineered Exos, those with the fusion protein containing three TPO-mimic peptides (CD63-mTPO 3 ), named as m 3 Exos, exhibited the h
