Likewise, Liu and colleagues demonstrated that the connection between OS malignant phenotypes and M2 polarization of TAMs is controlled by exosomal miR-221-3p, where miR-221-3p released from M2-polarized TAMs exosomes could augment tumor growth while reducing apoptosis through SOCS3/JAK2/STAT3 signaling [71]. Here, STAT3 is linked to neoplasm.
