Exosomes Derived From microRNA-540-3p Overexpressing Mesenchymal Stem Cells Promote Immune Tolerance via the CD74/Nuclear Factor-kappaB Pathway in Cardiac Allograft

BACKGROUNDHeart transplantation is a crucial intervention for severe heart failure, yet the challenge of organ rejection is significant. Bone marrow mesenchymal stem cells (BMSCs) and their exosomes have demonstrated potential in modulating
