Tiny bubbles that cells use to communicate with each other prolonged lifespan and reversed numerous aging phenotypes when taken from young mice and injected into old ones, even though the treatment started late in life [1]. The tiny messengers For millennia, humans credited young blood with rejuvenating qualities. This belief caused legendary and historic rulers...

In the Journal of Nanobiotechnology, researchers have found that embedding microvesicles in a slow-release hydrogel may be an effective treatment for osteoarthritis. A line of inquiry begins to bear fruit Researchers have repeatedly found that the extracellular vesicles (EVs) released by stem cells, particularly mesenchymal stem cells (MSCs), are the main drivers behind the effectiveness...

Researchers publishing in ACS Nano have described how culturing stem cells on nanogratings instead of flat substrates changes the effects of the extracellular vesicles (EVs) they send, potentially paving the way to a new system of therapies. When signaling is critical Many of the effects of stem cells can be traced back to the EVs,...

Resarchers publishing in Aging have found that extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (MSCs) reduce inflammatory markers in chondrocytes, which are responsible for building and maintaining human cartilage. An established approach This is far from the first attempt at treating osteoarthritis using stem cells. We have previously reported on a...

The Journal Club returns with Dr. Oliver Medvedik on September 29th at 12:00 Eastern time on our Facebook page. We take a look at a recent study published in Nature, in which extracellular vesicles derived from neonatal cardiac progenitors produced significant rejuvenation in old rats and human cells. Abstract Rejuvenation of an old organism was...

In a new study published in Nature, extracellular vesicles derived from neonatal cardiac progenitors produced significant rejuvenation in old rats and human cells [1]. Tiny messengers Extracellular vesicles (EV) are microscopic bubbles encased in the same lipid bilayer that cellular membranes are made of. EVs are secreted by cells, and they carry various molecular cargo...
