Old cells may regain a youthful phenotype when exposed to a young cell environment, say researchers in Nature this week. The results, say the authors, indicate that aged satellite cells have an ...

Researchers discovered that a protein called AP2A1 acts as a master switch controlling whether cells behave young or old When ...

"In response to the same thing, young cells go one way and old cells go another," said Chapman, who is now a postdoctoral ...

2 Interested in exploring this phenomenon further, the team monitored the available pool of iron and protein expression in blood stem cells of two- to three-month-old mice. The researchers found that ...

By sequencing the whole genomes of 1,305 blood stem cells from young and old mice, they were able to identify all the mutations present in each cell. These data were used to reconstruct "family ...

In an early-stage clinical trial, the therapy nearly doubled the expected survival time of young patients. Still, experts ...
