Abstract Extracellular vesicles (EVs) are emerging in tissue engineering as promising acellular tools, circumventing many of the limitations associated with cell‐based therapies. Epigenetic regulation through histone deacetylase (HDAC) inhibition has been shown to increase differentiation capacity. Therefore, this study aimed investigate potential augmenting osteoblast epigenetic functionality using HDAC inhibitor Trichostatin A (TSA) enhance therapeutic efficacy osteoblast‐derived EVs for...

While extracellular vesicles (EVs) continue to gain interest for therapeutic applications, their clinical translation is limited by a lack of optimal isolation methods. We sought determine how universally applied methods impact EV purity and yield. EVs were isolated ultracentrifugation (UC), polyethylene glycol precipitation, Total Exosome Isolation Reagent, an aqueous two-phase system with without repeat washes or size exclusion chromatography (SEC). EV-like particles could be detected all...

The application of extracellular vesicles (EVs) as natural delivery vehicles capable enhancing tissue regeneration could represent an exciting new phase in medicine. We sought to define the capacity EVs derived from mineralising osteoblasts (MO-EVs) induce mineralisation mesenchymal stem cell (MSC) cultures and delineate underlying biochemical mechanisms involved. Strikingly, we show that addition MO-EVs MSC significantly (P < 0.05) enhanced expression alkaline phosphatase, well rate volume...

Disseminated breast cancer cells have the capacity to metastasise bone marrow and reside in a dormant state within mesenchymal stem cell niche. Research has focussed on paracrine signalling factors, such as soluble proteins, microenvironment. However, it is now clear extracellular vesicles secreted by resident into this microenvironment also play key role initiation of dormancy. Dormancy encourages reduced proliferation migration, while upregulating adhesion, thus retaining Here, MCF7 were...

Osteoblast-derived extracellular vesicles (EV) are a collection of secreted (sEVs) and matrix-bound nanoparticles that function as foci for mineral nucleation accumulation. Due to the fact sEVs can be isolated directly from culture medium mineralising osteoblasts, there is growing interest their application regenerative medicine. However, at present therapeutic advancements hindered by lack understanding precise temporal contribution matrix mineralisation. This study advances current...

Abstract Background Skeletal muscle (SkM) regenerates following injury, replacing damaged tissue with high fidelity. However, in serious injuries, non-regenerative defects leave patients loss of function, increased re-injury risk and often chronic pain. Progress treating these has been slow, advances only occurring where a comprehensive understanding regeneration gained. Tissue engineering allowed the development bioengineered models SkM which regenerate injury to support research...
