Abstract:
Extracellular vesicles (EVs) possess the characteristics of their parent cells, based on which various studies have actively investigated treatments for diseases using mesenchymal stem cell-derived EVs due to their regenerative activity. Furthermore, in recent years, there have been significant efforts to engineer EVs to improve their native activities and integrate additional functions. Although both endogenous and exogenous methods are used for engineering EVs, endogenous methods may pose the problem of administering substances to cells undergoing metabolic changes, which can cause potential side effects. In addition, exogenous methods may have the limitation of losing beneficial factors inside EVs due to membrane disruption during engineering processes. Surface modification of EVs may also impair efficiency due to the presence of proteins on the EV surface. Therefore, in this study, a stable and efficient engineering method was achieved through the ethanol-mediated hybridization of EVs and functionalized lipid nanoparticles (LNPs) with a fusogenic lipid component. During hybridization, the internal bioactive factors and targeting moiety were maintained to possess the characteristics of both LNPs and EVs. The Ab-Hybrid, which was successfully synthesized through hybridization with nicotinamide-encapsulated and Col2A1 antibody-modified liposome and Transforming growth factor-β1 (TGF-β1)-overexpressed EVs, was administered to osteoarthritis (OA)-induced rats undergoing the destabilization of the medial meniscus surgery. Ultimately, the Ab-Hybrid demonstrated excellent chondroprotective and anti-inflammatory effects with targeting and long-lasting properties in OA lesions. We anticipate that this approach for manufacturing hybrid particles will serve as a valuable EV engineering method and a versatile platform technology applicable to various diseases.Keywords:

Organ and tissue loss through any injury motivate to formulate or develop new techniques that can generate tissues and decrease the dependency of transplantation. Regenerative medicine is an interdisciplinary field that solely depends on the principle of engineering and life science. These techniques used to fabricate cell sheets on biomaterials and then grafted it on host tissues to heal injury. Regenerative medicine involves use of substrate such a bioreactors and growth factors with cells and scaffold, which shows increase in the regenerative capacity of host tissues by using cell injection or immune modulation. Object of the present research is to reprograming of somatic cells to pluripotent cells that holds huge potential of regenerative medicine. Tissues are grafting in 3D construction by different techniques in tissue engineering. Bio-printing is an enabling technology of tissue engineering that promises to fabricate highly mimicked organs with a digital control. It gives the understanding of biomaterials and stem cell biology to integrate various printing mechanism for multi-phase tissue engineering.

Hydrogels (HGs), as three-dimensional structures, are widely used in modern medicine, including regenerative medicine. The use of HGs in wound treatment and tissue engineering is a rapidly developing sector of medicine. The unique properties of HGs allow researchers to easily modify them to maximize their potential. Herein, we describe the physicochemical properties of HGs, which determine their subsequent applications in regenerative medicine and tissue engineering. Examples of chemical modifications of HGs and their applications are described based on the latest scientific reports.

It is undoubtedly important for regenerative medicine to discover and use the cells of high proliferation and differentiation potentials. However, there are numerous cases where the tissue regeneration cannot be always achieved only by using the cells. Thus, an environmental site suitable for enabling cells to induce tissue regeneration is highly required for successful tissue regeneration. Tissue engineering is the biomedical technology or methodology indispensable to create this regeneration site while it makes use of the scaffold for cell proliferation and differentiation, the drug delivery system of biological signals, and their combination with cells. This paper describes the present status and research data of tissue engineering to emphasize the considerable significance in regenerative medicine.
