Baldness is an undesirable condition that afflicts both men and women, many of which have family members with significant hair loss. According to Health Day News, a new study of stem cells in mice shows promise for future treatments for people who battle hair loss.
The study was conducted on the fatty skin layers of mice by researchers at Yale University. Specifically, adipose precursor cells were found to spur new hair growth in mice, according to Health Day News.
Stem cells are present in hair follicles, which help generate hair growth. Health Day News explains that these cells are still present
While looking for mechanisms that might be relevant to restoring regenerative potential in older skeletal muscle, HSCI Executive Committee member, Amy Wagers, PhD, and her team, thought about mechanisms that had been studied for a long time evolutionarily as regulating lifespan and longevity. One example of such a mechanism is reduced calorie intake in the absence of malnutrition, also know as calorie restriction, which has been show to extend lifespan in many organisms.
In order to address the question of whether calorie restriction could also affect skeletal muscle regeneration, Wagers and her colleagues placed mice for 12 weeks
Researchers have reversed aging in old mice by injecting them with a longevity gene and rejuvenating their stem cells‘ regenerative potential.
The study by University of California-Berkeley biologists represents a major advance in understanding the molecular mechanisms behind aging, paving the way for the development of targeted treatments for age-related degenerative diseases.
The found that SIRT3, one among a class of proteins known as sirtuins, plays an important role in helping aged blood stem cells cope with stress, the journal Cell reports.
When they infused the blood stem cells of old mice with SIRT3, the treatment boosted the formation of new blood
A team at Keio University has used stem cells to cure mice whose hind legs were paralyzed due to spinal cord damage, the researchers reported Wednesday at a Tokyo symposium.
The team transplanted neural stem cells grown from human iPS cells.
Team leader Hideyuki Okano, a physiology professor at Keio, said it is the first time in the world in which the curative effects of “induced pluripotent stem cells,” or iPS cells, have been confirmed.
Currently, there is no effective treatment for spinal nerve damage and treatment using iPS cells gives hope of a cure.
“It is valuable that treatment using human iPS
