At the Salk Institute in La Jolla, Calif., scientists are trying to get time to run backward. Biological time, that is. In the first attempt to reverse aging by reprogramming the genome, they have rejuvenated the organs of mice and lengthened their life spans by 30 percent. The technique, which requires genetic engineering, cannot be […]

Stem cells produce a decoy protein to attenuate growth signals. Artificially regulating this pathway might help keep muscles supple in muscular dystrophy or during normal aging, researchers hope. Full article
The National Academy of Medicine announced today the election of 70 regular members and 9 international members during its annual meeting. Election to the Academy is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have demonstrated outstanding professional achievement and commitment to service. Dr. Thomas Rando […]
All quiescent on the fresh native myofiber, but… Stem cells typically lose the capacity to differentiate when cultured in vitro. Their potency appears to depend on preserving the quiescent state, which has been difficult to accomplish with traditional culture methods. In the body, stem cells reside in specialized microenvironments, or niches, with unique chemical and […]
We are often told that sleep is one of the most important elements of a healthy lifestyle, that it helps in the healing and repair of our heart and blood vessels – among other things. It turns out that sleep, or something very similar, is equally important for stem cells, helping them retain their power […]
