摘要

Mesenchymal stem cells (MSCs) are multipotent stem cells with critical functions, including immunomodulation, multidirectional differentiation, anti-inflammatory activity, tissue repair, and regeneration. Recent studies demonstrate that MSCs can enhance hematopoietic stem cell engraftment, mitigate graft-versus-host disease (GVHD), address transplant-related complications, and treat conditions such as immune thrombocytopenia (ITP) and severe aplastic anemia (SAA). These therapeutic effects are largely attributable to the immunomodulatory and anti-inflammatory properties of MSCs. However, in hematologic malignancies, MSCs can exert both pro-tumor and anti-tumor influences. Exosomes, which are extracellular vesicles derived from MSCs (MSC-EVs), not only replicate many MSC functions but also exhibit greater chemical stability and lower immunogenicity. These characteristics make MSC-EVs particularly significant in the context of hematopoietic stem cell transplantation (HSCT). This review provides a detailed overview of the roles and clinical applications of MSCs in hematologic diseases, the properties of MSC-EVs, and their emerging significance in HSCT.
