Extracellular vesicles from skin precursor-derived Schwann cells promote axonal outgrowth and regeneration of motoneurons via Akt/mTOR/p70S6K pathway.

ABSTRACT:

Background

Skin precursor-derived Schwann cells (SKP-SCs) have been shown to benefit the recovery of spinal cord injury (SCI) and peripheral nerve injury (PNI) with motor dysfunction. However, the effect of extracellular vesicles (EVs) from SKP-SCs responsible for neuroregeneration remains unknown.

Methods

Based on the obtainment and identification of rat SKP-SCs and their derived EVs, the primary rat injury model of motoneurons resulting from axotomy in vitro or nerve crush in vivo, as well as the secondary rat ischemic hypoxic injury model of motoneuron exposure to oxygen-glucose-deprivation (OGD) in vitro, were treated with EVs from skin precursor-derived Schwann cells (SKP-SC-EVs), respectively. Then, the axonal outgrowth and regrowth was observed an
