schwann cell-derived exosomal vesicles

Schwann cell-derived exosomal vesicles are nanoscale extracellular vesicles (exosomes) secreted by Schwann cells—the myelinating glia of the peripheral nervous system. These vesicles range from 30–150 nm in diameter and contain a variety of bioactive molecules including miRNAs, mRNAs, proteins, and lipids. They play a crucial role in intercellular communication and have demonstrated significant therapeutic potential for tissue regeneration and repair—particularly in neurological injuries such as spinal cord injury (SCI), traumatic brain injury (TBI), and peripheral nerve damage[1][2][5][6]. Schwann cell-derived exosomal vesicles promote axonal regeneration by modulating cellular processes like proliferation, differentiation, angiogenesis, neuroprotection, and inflammation reduction[2][4][5]. Their small size allows them to cross the blood-brain barrier efficiently with low immunogenicity compared to whole-cell therapies. Additionally, they can be engineered for targeted delivery or loaded with therapeutic agents[6].
