Rejuvenated skin
Publishing in Science, researchers have transplanted old human skin to young mice and witnessed a robust rejuvenation cascade that is probably triggered by vascular growth [1]. New life for old skin Our skin begins to age relatively early, and this conspicuous process gave rise to a centuries-old huge industry of skin care. Sadly, most of...
Turning back the clock
Vadim Gladyshev and his team have published a review in Aging Cell about the current techniques and innovations in rejuvenation biotechnology, providing an overview of how these researchers see the state of the field. The reversibility of aging The reviewers begin by discussing the connection between the perceived irreversibility of aging and the lack of...
Heterochronic Parabiosis
A preprint published on bioRxiv, whose authors include well-known biogerontologist Vadim Gladyshev, has shown us many interesting details of the effects that heterochronic parabiosis has on aging mice. An old concept studied in new depth Heterochronic parabiosis is the linking of the circulatory systems of young and aged animals. While the researchers note that this...
Electric brain
There has been a great deal of interest in the last few years in the potential regenerative properties of blood factors. This has led to two broad schools of thought: one in which there are regenerative factors in young blood that can be isolated, and another in which aged blood contains regenerative factors that cannot...
Blood cells
A team of researchers, including Dr. Tony Wyss-Coray, co-founder of Alkahest, has discovered that exposing young cells to aged blood causes their gene expression to become akin to aged cells. Signaling cells to act older We have known from the heterochronic parabiosis and plasmapheresis research performed by Dr. Irina Conboy's lab and similar work done...
The Journal Club returns this Tuesday, July 28th, at 12:00 PM EDT / 5 PM UK, with your host Dr. Oliver Medvedik, livestreamed to our Facebook page. We will be taking a look at the recent study published by Dr. Irina Conboy and her team [1]. The study showed that by replacing half of the...
