By virtue of their bioactive cargo associated with key developmental morphogens and other signaling elements, exosomes play critical roles in mechanistic pathways in development, organogenesis, wound healing and regeneration. These extracellular vesicles (EVs) have inherent therapeutic potential. Exosomes from human mesenchymal stem cells (MSCs) have been utilized in tissue regenerative medicine and have shown positive therapeutic effects.

Exosomes in tissue regeneration and repair

Exosomes are nano-scale (typically~30-150 nm in diameter) extracellular vesicles (EVs) released by almost all cells. They are also effective transport vesicles that can carry protein content in their cores, as well as on the surface lipid layer, and also contain many types of genetic information, including messenger RNA (mRNA), DNA, and small noncoding RNAs. These EVs are involved in many biological processes, such as cellular communication, cell community life cycle and immune system regulation. In recent years, exosomes have attracted extensive attention and research in tissue regeneration and repair. They have been studied and used to effectively promote the repair of tissue or organ defects, including the liver, heart, and kidneys. Exosomes could modulate a series of processes, such as renal glycerol reperfusion, cardiovascular disease ischemia, or hepatic fibrosis through the delivery of nucleic RNAs, thus promoting the reconstruction and functional recovery of these organs. In addition, Exosomes have also been reported to play an important role in the repair activities associated with bone and cartilage through their actions on chondrocytes, osteoblasts, osteoclasts, precursor cells, and immune cells.

Tissue regeneration and repair exosome research solution at Creative Proteomics

Cell-based therapy has significant beneficial effects on tissue repair and regeneration and is one of the current novel strategies in regenerative medicine. However, this method has a number of drawbacks. Exosomes provide an alternative therapy to cellular therapy for a variety of diseases because they are more stable and storable, without the risk of aneuploidy, and with a lower possibility of immune rejection after in vivo allogeneic administration.

  • Exosomes in the cartilage and bone tissue repair and regeneration

A more abundant source of functionally diverse exosomes has largely addressed the limitations of transplanted cell availability. Due to the naturally derived components, exosomes have fewer safety concerns, lower toxicity, and fewer immunogenicity issues than live cell transplants or synthetic implants. Thus, exosome-based therapy is considered a promising method to improve cartilage repair and bone growth in therapeutic applications.

  • Exosomes in soft tissue repair and regeneration

Soft tissue injuries, including skin, muscle, tendon, and nerve injuries, are common after trauma and tumor removal. Exosomes have been identified in existing studies for their potential in the tendon, skeletal muscle and peripheral nerve regeneration through different mechanisms, such as promoting myogenesis, increasing tendon cell differentiation and enhancing neural synapse growth, and so on.
