Extracellular vesicles from bone marrow mesenchymal stem cells alleviate acute rejection injury after liver transplantation by carrying miR‐22‐3p and inducing M2 polarization of Kupffer cells

BMSCs-EVs carry miR-22-3p into KCs and upregulate miR-22-3p, inhibit IRF8 expression, induce KC M2 polarization, and attenuate AR injury after liver transplantation.
