Extracellular vesicles (EVs) are a collective term for nanoscale or microscale secreted by cells that play important biological roles. Mesenchymal stem class of with the potential self-healing and multidirectional differentiation. In recent years, numerous studies have shown EVs, especially those mesenchymal cells, can promote repair regeneration various tissues and, thus, significant in regenerative medicine. However, due to rapid clearance capacity circulatory system, EVs barely able act persistently at specific sites target tissues. Hydrogels good biocompatibility loose porous structural properties allow them serve as EV carriers, thereby prolonging retention certain areas slowing release EVs. When needed function sites, EV-loaded hydrogels stand an excellent approach. this review, we first introduce sources, roles, extraction characterization methods describe their current application status. We then review different types discuss factors influencing abilities carry summarize several strategies loading into characterizing hydrogels. Furthermore, applications tissue repair. This article concludes summary state research on outlook future directions, which hope will provide promising ideas researchers.

Abstract Background With the widespread prevalence of neurodegenerative diseases (NDs) and high rates mortality disability, it is imminent to find accurate targets for intervention. There growing evidence that neuroimmunity pivotal in pathology NDs interventions targeting hold great promise. Exogenous or dislocated nucleic acids activate cytosolic DNA sensor cyclic GMP‐AMP synthase (cGAS), activating stimulator interferon genes (STING). The activated STING triggers innate immune responses then cGAS‐STING signaling pathway links abnormal acid sensing response. Recently, numerous studies have shown neuroinflammation regulated by plays an essential role NDs. Aims In this review, we summarized mechanism focused on inhibitors cGAS‐STING. Conclusion important pathogenesis Inhibiting may provide new measures treatment

Despite the massive efforts of modern medicine to stop evolution Alzheimer’s disease (AD), it affects an increasing number people, changing individual lives and imposing itself as a burden on families health systems. Considering that vast majority conventional drug therapies did not lead expected results, this review will discuss newly developing alternative in effort or slow AD. Focused Ultrasound (FUS) its derived Transcranial Pulse Stimulation (TPS) are non-invasive therapeutic approaches. Singly applied technique change permeability blood–brain–barrier (BBB), FUS TPS have demonstrated benefits use treating AD animal human studies. Adipose-derived stem Cells (ADSCs), gene therapy, many other methods (diet, sleep pattern, physical exercise, nanoparticle delivery) also new potential treatments since multimodal approaches represent trend disorder research therapies.

With aging, neural stem cells (NSCs) undergo age-related changes, including metabolic abnormalities, disrupted protein homeostasis, mitochondrial dysfunction, reduced genetic stability, and more notably, a diminished capacity for proliferation differentiation. These changes may contribute to the development of neurodegenerative diseases such as Alzheimer’s disease (AD) Parkinson’s (PD). In these conditions, disease-specific pathological interact with alterations NSCs, resulting in impairment neurogenesis, which further leads cognitive, mood, motor decline. Based on potential therapeutics targeting neurogenesis cell-based therapies restore functions NSCs replace degenerated neurons, aiming ameliorate functional decline diseases. While therapies, cell transplantation secretome therapy, show great treatment diseases, challenges tumorigenesis, immune rejection, extraction or storage need be addressed. A better understanding age- disease-related underlying mechanism driving benefits drawbacks therapeutic approaches provide insights novel disease-modifying interventions future

Abstract Tissue engineering holds promise for developing therapeutic applications using viscous materials e.g. hydrogels. However, assessing the cytotoxicity of such with conventional assays can be challenging due to non-specific interactions. To address this, we optimized a live/dead staining method quantitative evaluation and compared it CCK8 assay. Our MicroDrop involved seeding droplets containing 5000 cells in 10 µl medium on 12-well plates. After allowing them adhere 4 h, various samples were applied measurements conducted fluorescence microscope immediately at daily intervals up 72 h.
