Abstract

Mesenchymal stem cells (MSCs) have emerged as a promising therapeutic approach in the treatment of brain cancer due to their unique biological properties, including their ability to home tumor sites, modulate the tumor microenvironment, and exert anti-tumor effects. This review delves into the molecular mechanisms and pathways underlying MSC-mediated therapy in brain cancer. We explore the various signalling pathways activated by MSCs that contribute to their therapeutic efficacy, such as the PI3K/Akt, Wnt/β-catenin, and Notch pathways. Additionally, we discuss the role of exosomes and microRNAs secreted by MSCs in mediating anti-tumor effects. The review also addresses the challenges and future directions in optimizing MSC-based therapies for brain cancer, including issues related to MSC sourcing, delivery methods, and potential side effects. Through a comprehensive understanding of these mechanisms and pathways, we aim to highlight the potential of MSCs as a viable therapeutic option for brain cancer and to guide future research in this field.
