Invisibility
Gene editing can make stem cells invisible to the immune system, making it possible to carry out cell therapy transplants without suppressing the patients' immune response [1]. Help me help you Cellular therapies involve transplanting cells into a patient to replace the activity of malfunctioning or damaged cells. For example, cardiomycetes could be transplanted to...
Stem cell development
A new study published in the FASEB Journal shows how mesenchymal stem cells derived from adipose tissue (ADSCs) reverse some effects of aging in nearby cells. It's not the cells themselves, it's what they secrete The original and ongoing main purpose of stem cell therapies is to directly combat stem cell exhaustion: to replenish the...
Blood cells
Researchers have reversed the age-related decline in the function of hematopoietic stem cells (HSCs) in older mice using nicotinamide riboside. This success can make our blood more youthful and increase the effectiveness of stem cell transplantation [1]. There will be blood HSCs are the progenitors of all our blood cells. HSCs reside in the bone...
Interview image for Prof. Melissa Harris
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
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]. Why we age: Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand...
Dr. Hanadie Yousef
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...
