Abstract

A common surgical disease, intervertebral disc degeneration (IVDD), is increasing at an alarming rate in younger individuals. Repairing damaged intervertebral discs (IVDs) and promoting IVD tissue regeneration at the molecular level are important research goals. Exosomes are extracellular vesicles (EVs) secreted by cells and can be derived from most body fluids. Mesenchymal stem cell-derived exosomes (MSC-exos) have characteristics similar to those of the parental MSCs. These EVs can shuttle various macromolecular substances, such as proteins, messenger RNAs (mRNAs), and microRNAs (miRNAs) and regulate the activity of recipient cells through intercellular communication. Reducing inflammation and apoptosis can significantly promote IVD regeneration to facilitate the repair of the IVD. Compared with MSCs, exosomes are more convenient to store and transport, and the use of exosomes can prevent the risk of rejection with cell transplantation. Furthermore, MSC-exo-mediated treatment may be safer and more effective than MSC transplantation. In this review, we summarize the use of bone marrow mesenchymal stem cells (BMSCs), adipose-derived mesenchymal stem cells (AMSCs), nucleus pulposus mesenchymal stem cells (NPMSCs), and stem cells from other sources for tissue engineering and use in IVDD. Here, we aim to describe the role of exosomes in inhibiting IVDD, their potential therapeutic effects, the results of the most recent research, and their clinical application prospects to provide an overview for researchers seeking to explore new treatment strategies and improve the efficacy of IVDD treatment.

Keywords: Intervertebral disc degeneration, mesenchymal stem cells, exosome, mechanism, challenge, surgical disease.
