And Function

Extracellular vesicles (EVs) are nanometer-sized, lipid membrane–enclosed vesicles secreted by most, if not all, cells and contain lipids, proteins, and various nucleic acid species of the source cell. EVs act as important mediators of intercellular communication that influence both physiological and pathological conditions. Given their ability to transfer bioactive components and surmount biological barriers, EVs are increasingly being explored as potential therapeutic agents. EVs can potentiate tissue regeneration, participate in immune modulation, and function as potential alternatives to stem cell therapy, and bioengineered EVs can act as delivery vehicles for therapeutic agents. Here, we cover recent approaches and advances of EV-based therapies.

Cord Injury

: Spinal cord injury is a devastating condition that is critically challenging and progressive, needing immediate medical attention due to its complex pathophysiology and affecting the social status and economic burden. Stem cell therapy has been the emerging therapeutic trend to treat various diseases for decades. Mesenchymal stem cells pose more advantages over other stem cells in immune-modulation, immune evasiveness, self-renewal, multipotency, etc. Due to various issues in the recent past related to allogenic transplants, ethical concerns in obtaining tissues and adult cells, host immune response, GMP grade production and certification, cell-derived products or cell secretome have proven to be a promising approach and have been implicated in many studies and also in many clinical trials. Utilization of these human MSC-derived exosomes/extracellular vesicles in spinal cord injury has also been demonstrated in many pre-clinical animal models. It is now proven to be therapeutically more efficient and safer than cell therapy. This review focuses on employing human MSC derived EVs for SCI and continues to elucidate the recent advances and emerging EVs trends from other cell types. We discuss biomaterial-based synergistic intervention, mention mimetics and nanovesicles and finally touch upon safety concerns in EV therapy.

Cellular Labeling

Rapidly ageing populations are beset by tissue wear and damage. Stem cell-based regenerative medicine is considered a solution. Years of research point to two important aspects: (1) the use of cellular imaging to achieve sufficient precision of therapeutic intervention, and the fact that (2) many therapeutic actions are executed through extracellular vesicles (EV), released by stem cells. Therefore, there is an urgent need to interrogate cellular labels in the context of EV release. We studied clinically applicable cellular labels: superparamagnetic iron oxide nanoparticles (SPION), and radionuclide detectable by two main imaging modalities: MRI and PET. We have demonstrated effective stem cell labeling using both labels. Then, we obtained EVs from cell cultures and tested for the presence of cellular labels. We did not find either magnetic or radioactive labels in EVs. Therefore, we report that stem cells do not lose labels in released EVs, which indicates the reliability of stem cell magnetic and radioactive labeling, and that there is no interference of labels with EV content. In conclusion, we observed that direct cellular labeling seems to be an attractive approach to monitoring stem cell delivery, and that, importantly, labels neither locate in EVs nor affect their basic properties.
