Research progress of exosomes in treating spinal cord injury / 基础医学与临床

Exosomes are membrane vesicles secreted by cells into the extracellular environment. Exosomes are a new cell component in the treatment of spinal cord injury. Exosomes are secreted by mesenchymal stem cells have anti-apoptotic, anti-inflammatory and pro-angiogenic effects in the treatment of spinal cord injury, which play a key role in nerve cell-cell communication and can delivery exogenous genetic material. Exosomes can penetrate blood-brain barrier and are more stable than their parent cells, reducing the safety risks in the administration of viable cells.
