Acute myelogenous leukemia (AML)-derived mesenchymal stem cells (MSCs) (AML-MSCs) have been identified to play a significant role in AML progression. The functions of MSCs mainly depend on their paracrine action. Here, we investigated whether AML-MSCs functioned in AML cells by transferring METTL14 (Methyltransferase 14) into AML cells via exosomes.

The results revealed 39 mutations in the three esophageal cancer cell lines; the genes with the highest mutation frequencies included mitochondrially encoded cytochrome B (MT‑CYTB), NADH dehydrogenase 5 (MT‑ND5) and MT‑ND4 gene.
