Scientists showed that hair loss happens partially as a result of stem cells escaping from hair follicles. They also shot a stunning time-lapse video of the process. The stem cell cycle Stem cells reside in “stem cell compartments” in various tissues. By differentiating into multiple types of cells upon demand, they contribute to tissue regeneration....

A review published in The Malaysian Journal of Medical Sciences has outlined what effects caloric restriction (CR) has on the development and differentiation of stem cells. Stem cells and their exhaustion The reviewers began by discussing stem cell exhaustion, a hallmark of aging and a common concern of aging research that we have covered extensively....

Researchers have shown that age-related loss of bone maintenance is caused by changes in gene expression [1]. Perhaps most importantly, those changes can also be reversed and the bone marrow stem cells rejuvenated. Bones become weaker as we age as stem cell function declines With advancing age, it is typical for our bones to become...

A study conducted by researchers at the University of Taipei in Taiwan has shown that the ginseng derivative Rg1 decreases the cellular senescence marker p16INK4a in fitness-trained men 24 hours after exercise. An experiment to link p16INK4a, aging, exercise, and Rg1 The cell cycle inhibitor p16INK4a, which is also a well-known biomarker of senescent cells,...

Muscular degradation with age isn’t the result of a decline in the intrinsic regenerative ability of muscles, according to new research [1]. Instead, sarcopenia is likely due to changes in the muscle microenvironment that reduce repair and regeneration. Declining muscles Age-related muscle loss can begin as early as a person’s fourth decade, and sarcopenia can...

A new article published in Aging and Disease has taken a look at what two stem cell-activating growth factors can do in aged mice with Alzheimer's-like pathology. Alzheimer's disease (AD) is perhaps the most age-related of all age-related diseases. Perhaps not coincidentally, it has also been the most stubborn disease to develop treatments for. One...
