Injectable exosome-functionalized extracellular matrix hydrogel for metabolism balance and pyroptosis regulation in intervertebral disc degeneration
Overview
Paper Summary
This study developed an injectable, temperature-sensitive hydrogel (dECM@exo) composed of decellularized extracellular matrix and adipose-derived mesenchymal stem cell exosomes for the treatment of intervertebral disc degeneration (IVDD). The dECM@exo hydrogel was shown to be biocompatible, promote matrix synthesis, and inhibit pyroptosis in nucleus pulposus cells in vitro, and it also ameliorated IVDD in a rat model in vivo.

Rating Explanation
This study presents a novel approach to treating IVDD using an injectable hydrogel system that combines the benefits of ECM and exosomes. The methodology is generally sound, and the results demonstrate promising therapeutic potential. However, some limitations, such as the short follow-up period and the use of a rat model, prevent a higher rating.
