Exosomes, nanosized extracellular vesicles (30-150 nm) secreted by various cell types, have emerged as crucial mediators of intercellular communication and promising therapeutic agents. This review highlights the diverse RNA cargo of exosomes derived from human umbilical cord mesenchymal stem cells (HucMSC-Exos), including mRNAs, miRNAs, long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), which regulate gene expression and cellular functions in target cells. The mechanisms of exosome biogenesis, release, and uptake are discussed, with emphasis on their ability to cross biological barriers such as the blood - brain barrier. HucMSC-derived exosomes exhibit therapeutic potential in wound healing, angiogenesis, neuroprotection, immunomodulation, and treatment of diseases like Parkinson's, preeclampsia, and renal or hepatic injury. Specific exosomal miRNAs, such as miR-136, miR-335-5p, and miR-1246, demonstrate targeted effects. Additionally, exosomal RNAs show promise as disease biomarkers. Future directions involve standardization, targeted engineering, RNA profiling, clinical trials, and integration into personalized medicine strategies for regenerative therapy.
