Researchers turned their attention to exosomes, which are secreted by cells in the body as a way of communic<br>g.They can transfer information such as DNA, RNA or proteins between cells, which can affect the function of the recipient cell. <br> Professor Ke Cheng and colleagues wanted to see if a dose of exosomes from human skin cells could reduce wrinkles in mic<br> Professor Cheng said: ‘Think of an exosome as an envelope with instructions inside – like one cell mailing a letter to another cell and telling it what <br>o.’In this case, the envelope contains microRNA, non-coding RNA that instructs the recipient cell to produce more collag<br> The researchers exposed mice to ultraviolet B (UVB) light, which accelerates aging and 식물 엑소즘 causes wrinkles to <br>.

To avoid having to inject the exosomes with a needle, the team used a device that uses a jet of air to deliver medications deep into the <br>. Three weeks later, the treated mice showed significantly thinner wrinkles than the untreated mice due to the boost in <br>agen.Skin from the mice treated with exosomes was around 20 per cent thicker than that of rodents which didn’t receive any t<br>ment.It was also five per cent thicker than the mice given MSC – an anti-wrinkle treatment using stem cells derived from bone <br>ow. MSCs – mesenchymal stem cells – are a particular type of adult stem cell being investigated as an ‘ultimate’ anti-ageing<br>rapy.There was 30 per cent more collagen production in skin treated with the exosomes than MSC trea<br>skin.The exosomes also worked better than topical retinoic acid, a standard anti-aging cream, used on another group o<br>ce. Professor Cheng said there are two major benefits to exosome treatments over conventional tr<br>ents.’One, you can use donor skin cells from anyone to grow and harvest these exosomes – they aren’t cells, so you don’t run the risk of rej<br>on. ‘And two, the treatment can be administered without needles – exosomes are small enough to be able to penetrate the skin via pressure, or jet injection <br>ods.’Botox temporarily reduces wrinkles by paralysing muscles in the face, which can cause a ‘frozen fa<br>look.It also comes with risks, as do dermal fillers, if not done pr<br>ly. Professor Chen said: ‘Our hope is eventually people may be able to “bank” skin samples and come back to them, or use donor exosome treatments that they can administer them<br>es. ‘We believe that this work is an important step toward potentiating future human clinical trials in the prevention and treatment of cutaneous <br>g.’ The findings were published in the journal American Chemical Societ<br>no.
