Research overview

In this study, we investigated the efficacy of MSC-sEV for protection against ouabain-induced SGN degeneration. In conclusion, our findings demonstrate the potential of MSC-sEV in preventing SGN degeneration and promoting neural growth, suggesting intratympanic injection of MSC-sEV is a specific and efficient strategy for neural hearing loss.

Key findings

Sensorineural hearing loss is one of the most prevalent sensory deficits.

Spiral ganglion neurons (SGNs) exhibit very limited regeneration capacity and their degeneration leads to profound hearing loss.

Mesenchymal stem cell-derived small extracellular vesicles (MSC-sEV) have been demonstrated to repair tissue damage in various degenerative diseases.

However, the effects of MSC-sEV on SGN degeneration remain unclear.
