Published: Aug. 17, 2023

Abstract Skin wounds are characterized by injury to the skin due trauma, tearing, cuts, or contusions. As such injuries common all human groups, they may at times represent a serious socioeconomic burden. Currently, increasing numbers of studies have focused on role mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in wound repair. cell-free therapy, MSC-derived EVs shown significant application potential field repair as more stable and safer option than conventional therapy. Treatment based can significantly promote damaged substructures, including regeneration vessels, nerves, hair follicles. In addition, inhibit scar formation affecting angiogenesis-related antifibrotic pathways promoting macrophage polarization, angiogenesis, proliferation, migration, inhibiting excessive matrix production. Additionally, these structures serve scaffold for components used repair, be developed into bioengineered support trauma Through formulation standardized culture, isolation, purification, drug delivery strategies, exploration detailed mechanism will allow them clinical treatments conclusion, EVs-based therapies important prospects Here we provide comprehensive overview their current status, potential, associated drawbacks.

Abstract The healing process at a wound is made up of many types cells, growth factors, the extracellular matrix, nerves and blood vessels all interacting with each other in complex changing ways. Microbial colonization proliferation are possible place injury, which makes infection more likely. Because this, any cut has chance getting an infection. Researchers have found that infections make patients upset cost healthcare system lot money. Surgical site happen to people who recently had surgery. This study shows such surgical linked high rate illness death. shown by fact 25% get serious sepsis need be transferred intensive care unit. In both animal models people, mesenchymal stem cells (MSCs) play active role stages positive effects. Exosomes one main things MSCs release. They effects similar those parent MSCs. Various effector proteins, messenger RNA microRNAs can transported vesicles control activity target cells. big impact on process. These results suggest using MSC-exosomes as new type cell-free therapy could better safer option than whole cell therapy. review mostly about how use parts help heal.

Understanding exosomes: Part 2—Emerging leaders in regenerative medicine

Periodontology 2000, Journal Year: 2024, Volume and Issue: 94(1), P. 257 - 414

Published: Feb. 1, 2024

Abstract Exosomes are the smallest subset of extracellular signaling vesicles secreted by most cells with ability to communicate other tissues and cell types over long distances. Their use in regenerative medicine has gained tremendous momentum recently due their be utilized as therapeutic options for a wide array diseases/conditions. Over 5000 publications currently being published yearly on this topic, number is only expected dramatically increase novel strategies continue developed. Today exosomes have been applied numerous contexts including neurodegenerative disorders (Alzheimer's disease, central nervous system, depression, multiple sclerosis, Parkinson's post‐traumatic stress disorders, traumatic brain injury, peripheral nerve injury), damaged organs (heart, kidney, liver, stroke, myocardial infarctions, ovaries), degenerative processes (atherosclerosis, diabetes, hematology musculoskeletal degeneration, osteoradionecrosis, respiratory disease), infectious diseases (COVID‐19, hepatitis), procedures (antiaging, bone regeneration, cartilage/joint osteoarthritis, cutaneous wounds, dental dermatology/skin erectile dysfunction, hair regrowth, intervertebral disc repair, spinal cord vascular regeneration), cancer therapy (breast, colorectal, gastric osteosarcomas), immune function (allergy, autoimmune regulation, inflammatory diseases, lupus, rheumatoid arthritis). This scoping review first its kind aimed at summarizing extensive potential broad range disorders.

Adipose stem cells in tissue regeneration and repair: From bench to bedside

Regenerative Therapy, Journal Year: 2023, Volume and Issue: 24, P. 547 - 560

Published: Oct. 11, 2023

ADSCs are a large number of mesenchymal stem cells in Adipose tissue, which can be applied to tissue engineering. have the potential multi-directional differentiation, and differentiate into bone cardiac urothelial cells, skin etc. Compared with other multitude promising advantages, such as abundant number, accessibility cell culture, stable function, less immune rejection. There two main methods use for repair regeneration. One is implant "ADSCs-scaffold composite" injured site promote The cell-free therapy: using ADSC-exos or ADSC-CM alone release miRNAs, cytokines bioactive substances regeneration regulated by variety cytokines, signaling molecules, external environment. differentiation different tissues also induced growth factors, ions, hormones, scaffold materials, physical stimulation, factors. specific mechanisms complex, most pathways need further explored. This article reviews summarizes mechanism clinical application injury so far, puts forward problems that solved this field, hoping provide directions research field.

An injectable, activated neutrophil-derived exosome mimetics/extracellular matrix hybrid hydrogel with antibacterial activity and wound healing promotion effect for diabetic wound therapy

Journal of Nanobiotechnology, Journal Year: 2023, Volume and Issue: 21(1)

Published: Aug. 30, 2023

Chronic diabetic wounds are primarily caused by infection, inflammation, and angiogenesis-related disorders. An ideal approach for treating chronic is combining anti-infection strategies, immune microenvironment regulation, angiogenesis promotion. Vascular endothelial growth factor (VEGF) can promote the proliferation migration of vascular cells, thereby promoting angiogenesis. However, low stability inability to target lesions limit its application. Polymorphonuclear neutrophil-derived exosomes (PMNExo) exhibit good delivery properties be used therapeutic VEGF. Furthermore, they retain antibacterial ability polymorphonuclear neutrophils (PMNs). Nonetheless, PMNExo generation impedes applications. In this study, we prepared exosome mimetics (EM) from PMNs using extrusion process; as a result, yield significantly improved. To increase residence exosomes, an extracellular matrix (ECM) hydrogel, thermosensitive material that function in situ gel vivo, was carrier. The active peptides ECM regulated wound. summary, loaded with VEGF-encapsulated activated neutrophil (aPMNEM) develop VEGF-aPMNEM-ECM hybrid hydrogel wounds. accelerates regeneration Our study provides prospective therapy platform involving cytokines different diseases.

Wound repair is a complex problem for both clinical practitioners and scientific investigators. Conventional approaches to wound have been associated with several limitations, including prolonged treatment duration, high expenses, significant economic psychological strain on patients. Consequently, there pressing demand more efficacious secure modalities enhance the existing landscapes. In field of repair, cell-free therapy, particularly use mesenchymal stem cell-derived exosomes (MSC-Exos), has made notable advancements in recent years. Exosomes, which are small lipid bilayer vesicles discharged by MSCs, harbor bioactive constituents such as proteins, lipids, microRNA (miRNA), messenger RNA (mRNA). These facilitate material transfer information exchange between cells, thereby regulating their biological functions. This article presents comprehensive survey function mechanisms MSC-Exos context healing, emphasizing beneficial impact each phase process, regulation immune response, inhibition inflammation, promotion angiogenesis, advancement cell proliferation migration, reduction scar formation.
