Stem cells supply the specialized cells that make up our tissues and organs; every time existing cells are lost for whatever reason, stem cells that can differentiate into that particular type of cell jump into action to compensate for the loss. However, this ability declines over time as aging progresses; indeed, stem cell exhaustion is…

A new open access paper takes a look at the potential of regenerative medicine for the treatment of Alzheimer’s disease [1]. The review covers approaches such as spurring the production of new neurons and transplanting new neurons while taking a look at the disease-modeling approaches and techniques that science is now using to refine approaches…

Korean and Singaporean scientists have recently proposed a new probe to detect cancer stem cells, and it might be an effective seek-and-destroy weapon against a variety of cancer types. In a paper published in the journal Angewandte Chemie earlier this month, the researchers describe a fluorescent dye that they created to highlight cancer stem cells,…

Researchers at the USC Roski Eye Institute, in collaboration with other institutions in California, have shown that a new stem cell-based retinal implant could help people with dry age-related macular degeneration. The researchers have published the results of their phase 1/2a study in the journal Science Translational Medicine [1]. What is dry age-related macular degeneration?…

Researchers at the School of Molecular Sciences at Arizona State University have discovered a potential way to supercharge our stem cells and reverse some aspects of cellular aging. The Hayflick limit Normal cells cannot divide indefinitely; they have a built-in replicative limit, which is often called the Hayflick limit after its discoverer, Leonard Hayflick. This…

Today, we wanted to highlight more progress in a rapidly advancing area of medicine and talk about a new study that uses an exosomes-based approach for stroke treatment that repairs brain tissue. A stem cell-based approach to treating stroke Professor Steven Stice from the University of Georgia (UGA) and Nasrul Hoda of Augusta University led…

What if I told you that we could regenerate our teeth? Well, that may soon be a possibility thanks to new research showing that teeth can be encouraged to regrow. Rather than drilling holes into teeth and plugging them with artificial fillers, dentists in the near future may be able to rebuild your teeth with…

As we age, our bodily functions begin to deteriorate. To some extent, our bodies can cope with these unwelcome changes, but after age 35, some of them become visible. For us living in a world where youth and physical attractiveness are considered an advantage, this gradual loss of young looks can be painful – or…

Stem cell therapies have been developing and evolving rapidly over the last decade, and extracellular vesicles (EVs) are another innovative approach that researchers are exploring. EVs are being explored for their potential as the basis of new cell therapies, taking the signals generated from various types of stem cells and delivering just those signals, rather…

Researchers have found that by manipulating a single RNA molecule, they can reverse some aspects of cellular aging and regenerate aged cells. Old cells resist regeneration As we grow older, our cells gradually age, leading to the development of various diseases. Therefore, inducing cellular regeneration is one of the approaches that researchers are using to…
