Effect of adipokines on bone marrow mesenchymal stem cell function.

During excessive adipose tissue accumulation, various adipokines such as visfatin, chemerin, vaspin, and adiponectin are released into systemic circulation, thereby influencing metabolic tissue function throughout the body. As multifunctional signaling molecules secreted by adipose tissue, adipokines play a pivotal role in metabolic regulation, inflammatory response, and tissue homeostasis. Recent studies have demonstrated that adipokines can influence skeletal system repair and regeneration by modulating bone marrow-derived mesenchymal stem cell (BMSC) proliferation, differentiation, migration, and immunomodulatory functions. However, different adipokines have distinct roles in regulating BMSC function, but their underlying molecular mechanisms are not fully understood. In this review, we systematically summarize the specific mechanisms of action and potential clinical applications of visfatin, chemerin, vaspin, and adiponectin on BMSC function in order to reveal new mechanisms of interaction between adipokines and BMSCs. The aim is to provide a theoretical basis for targeted treatment strategies for bone diseases targeting adipokines.
