By our late 30s, most of us have a growing number of gray hairs. They just show up one day, unannounced, and they continue to hang out, usually unwelcomed. Then, they multiply, steadily, inexorably. That little party becomes a larger party, and eventually the party takes over and kicks everyone else out. Some of us...
Chromosomes and telomere loss
December 15, 2020
Scientists have discovered a new telomere-protecting mechanism in embryonic stem cells. This discovery can bring us closer to solving the notorious problem of telomere attrition and to understanding the immortality of cancer cells [1]. Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand base pairs, yet...

December 11, 2020
In this presentation given at Ending Age-Related Diseases 2020, Dr. Hanadie Yousef of Juvena Therapeutics discusses the secretome, the signaling system of cells that affect the behavior of other cells. The secretome of embryonic stem cells encourages other cells to grow and develop, proiding a rejuvenative effect. Isolating these proteins and introducing them into aging...
Cartilage cells
October 28, 2020
New research published in Stem Cell Research and Therapy has improved the regenerative potential of chondrocytes in vitro. CartilageCartilage tissue is found in various places throughout the human body, including the ears, the nose, between the ribs, and the trachea. While trauma can compromise cartilage in each of these locations, most cartilage problems occur at...
October 13, 2020
In a review paper, a group of scientists highlight a new strategy that addresses the shortcomings of stem cell therapy by adding T cell progenitors to the graft [1]. Adaptive Immune SystemThe adaptive immune system is a marvel that only vertebrates are blessed with. This complex mechanism protects us from a wide variety of threats,...

August 25, 2020
A collective of scientists has shown that osteoarthritis can be alleviated by guiding skeletal stem cells towards differentiation into chondrocytes, which are responsible for producing healthy cartilage [1]. Osteoarthritis (OA) is a classic example of an age-related disease. While almost non-existent in younger people, it affects as much as half of the over-65 population worldwide....
