Exosomes are small extracellular vesicles that play a crucial role in intercellular communication and the transfer of biomolecules between cells. These tiny structures, typically ranging from 30 to 150 nanometers in diameter, are released by various cell types and can be found in numerous bodily fluids, including blood, urine, and saliva. Exosomes contain a cargo of proteins, lipids, RNA molecules (such as mRNA, miRNA, and other non-coding RNAs), and even DNA fragments, reflecting the composition of their parent cells.

How it works

Secretion: Exosomes are released by cells into the extracellular environment through a process known as exocytosis. They are formed within the endosomal system as intraluminal vesicles (ILVs) within multivesicular bodies (MVBs). These MVBs then fuse with the cell membrane, releasing exosomes into the extracellular space.

Cellular Uptake: Once released, exosomes can interact with neighboring or distant recipient cells. They can be internalized by recipient cells through various mechanisms, including endocytosis, phagocytosis, or direct fusion with the cell membrane.

Bioactive Cargo Delivery: Exosomes carry a cargo of bioactive molecules, including proteins, lipids, and nucleic acids. Upon internalization by recipient cells, exosomes deliver their cargo, thereby modulating various cellular processes such as gene expression, protein synthesis, and signaling pathways.

Cellular Effects: The bioactive molecules carried by exosomes can elicit a wide range of cellular effects depending on their composition and the recipient cell type. These effects may include promoting cell proliferation, modulating immune responses, inducing tissue repair and regeneration, and enhancing cellular homeostasis and function.

In regenerative medicine and therapeutics, exosomes derived from stem cells have gained significant attention due to their potential therapeutic properties. Stem cell-derived exosomes contain a rich and diverse array of bioactive molecules that can exert beneficial effects on recipient cells and tissues. These effects may include promoting tissue regeneration, reducing inflammation, and enhancing tissue repair processes.

Frequently asked questions

Exosomes are small extracellular vesicles that are released by various cell types. They contain a cargo of proteins, lipids, and nucleic acids, including RNA and DNA fragments.

Exosomes play a crucial role in intercellular communication by transferring biomolecules between cells. They influence various physiological processes and contribute to the regulation of immune responses, tissue repair, and disease progression.

Exosomes can be found in various bodily fluids, including blood, urine, saliva, cerebrospinal fluid, and breast milk. They are also present in cell culture supernatants and tissue extracts.

Exosomes can be isolated from biological fluids or cell culture supernatants using techniques such as ultracentrifugation, density gradient centrifugation, size exclusion chromatography, or commercial exosome isolation kits. They are characterized based on their size, morphology, surface markers, and molecular cargo using methods such as electron microscopy, nanoparticle tracking analysis, flow cytometry, and Western blotting.

Exosomes hold promise for various biomedical applications, including diagnostics, therapeutics, and drug delivery. They can serve as biomarkers for disease diagnosis and prognosis, as well as vehicles for the delivery of therapeutic agents such as nucleic acids, proteins, and drugs.

Blow Media have just launched our brand swanky new website and, excuse the pun, we are blown away. Scott, Ross and Rik nailed the brief we gave them and have gone above and beyond to produce a cracking website. It was also excellent value for money! The team were responsive throughout and were understanding and cool about last minute changes and design tweaking. I couldn't recommend them highly enough!

Best Website Design Agency in Berkshire in my view, perhaps the best in the UK. Have built 5 websites with them for clients in London, Leamington and Berkshire and every-time they knock it out the park.

This is an example of what our target clients are saying...“I have just looked at your new website….It does look amazing!!!! Very fresh, modern, vibrant and clear and simple to navigate. :)”. Exactly what we want - Scott and his team have delivered against the brief for our new website. Can't recommend them highly enough.

We have worked with Blowmedia closely to build two websites. I am not a very techy person and was daunted by the whole process, Scott explained everything to me in a way I could understand, always at the end of the phone or contactable by email and the whole process dealing with him and his team was easy and painless. The website is very professional and easy to navigate and has instantly from being launched started to attract new patients. I would highly recommend Scott and the Blowmedia's team to build any website.

I initially spoke to a member of Blow Media's team at a trade show and was very impressed with what they had to offer and with the websites they had already built which I was able to look at on my phone as I queued up to speak to somebody. The initial meeting was followed up very promptly that following week with an email and a fully detailed proposal of what they could offer which was very easy to follow, explaining fully all their services and a breakdown of their costs. I had already researched web designers thoroughly and soon realised that Blow Media, from my initial meeting and early correspondance, was the company I was going to use. From day one they were very proactive and led the whole process. Scott the MD came to see us and very quickly fully understood and visualised what we wanted to achieve perfectly. He also recommended a content writer, an SEO company, a company to do some filming in the clinic and a photographer. We used all his contacts other than the photographer which we decided to try and do ourselves but have since decided to use the photographer Blow Media initially recommended as my photography was the only thing I could criticise about my website. I would highly recommend Blow Media and their whole team, I have already instructed them to start work on our second website as our first website is already delivering and the clinic has never been busier.

Blow Media built our first website back in 2011. They worked closely with us and were able to deliver an outstanding, well presented website that enabled us to get found on search engines. After our business continued to grow we commissioned a second website in 2014 and then our third website was built in 2018. Our experience from start to finish has been fantastic With a special mention for Tracy and Scott who always make the process a joy. I would highly recommend the team and have many times already!
