ABSTRACT
Mesenchymal stem cells are a kind of pluripotent stem cells that play a role in stroke treatment mainly through paracrine mechanisms. Recent studies have shown that mesenchymal stem cell-derived exosomes play an important role in reducing post-stroke injury, promoting neural repair and angiogenesis. This article describes the research progress of bone marrow mesenchymal stem cell-derived exosomes in the treatment of stroke, and investigates the therapeutic mechanism and application prospects of exosomes bioactive substances represented by microRNAs.
ABSTRACT
Exosomes are extracellular vesicles released from various cellular sources and are widely present in body fluids. Bioactive substances such as microRNAs, mRNAs, and proteins are encapsulated in exosomes, which can activate various signaling pathways and play important roles in early warning of stroke and neurovascular unit repair. This article reviews the signal transduction of exosomes in cerebral ischemia.
