Scientists at the University of California, Berkeley, have identified a new molecular pathway critical to aging, and confirmed that the process can be manipulated to help make old blood like new again. The researchers found that blood stem cells' ability to repair damage caused by inappropriate protein folding in the mitochondria, a cell's energy station, is critical to their survival and regenerative capacity. The discovery, to be published in the March 20 issue of the journal Science, has implications for research on reversing the signs of aging, a process thought to be caused by increased cellular stress and damage. "Ultimately, a cell dies when it can't deal well with stress," said study senior author Danica Chen, an assistant professor in the Department of Nutritional Sciences and Toxicology. "We found that by slowing down the activity of mitochondria in the blood stem cells of mice, we were able to enhance their capacity to handle stress and rejuvenate old blood. This confirms the significance of this pathway in the aging process." Mitochondria host a multitude of proteins that need to be folded properly to function correctly. When the folding goes awry, the mitochondrial unfolded-protein response, or UPRmt, kicks in to boost the … Continue reading →

Experiments placed Sox9 at the crux of a shift in gene expression associated with hair follicle stem cell identity IMAGE:Researchers made stem cells fluoresce green (at the base of hair follicles above) by labeling their super-enhancers, regions of the genome bound by gene-amplifying proteins. It appears one such protein,... view more Credit: Laboratory of Mammalian Cell Biology and Development at The Rockefeller University/Nature Stem cells can have a strong sense of identity. Taken out of their home in the hair follicle, for example, and grown in culture, these cells remain true to themselves. After waiting in limbo, these cultured cells become capable of regenerating follicles and other skin structures once transplanted back into skin. It's not clear just how these stem cells -- and others elsewhere in the body -- retain their ability to produce new tissue and heal wounds, even under extraordinary conditions. New research at Rockefeller University has identified a protein, Sox9, that takes the lead in controlling stem cell plasticity. In a paper published Wednesday (March 18) in Nature, the team describes Sox9 as a "pioneer factor" that breaks ground for the activation of genes associated with stem cell identity in the hair follicle. "We found that … Continue reading →

In a paper published Wednesday (March 18) in Nature, the team describes Sox9 as a pioneer factor that breaks ground for the activation of genes associated with stem cell identity in the hair follicle. We found that in the hair follicle, Sox9 lays the foundation for stem cell plasticity. First, Sox9 makes the genes needed by stem cells accessible, so they can become active. Then, Sox9 recruits other proteins that work together to give these stemness genes a boost, amplifying their expression, says study author Elaine Fuchs, Rebecca C.

MIAMI (PRWEB) March 17, 2015 GlobalStemCellsGroup.com has announced plans to participate in the 25th annual Argentine Congress of Aesthetic Medicine April 9 and 10 2015. More than 1,000 physicians from around the world will descend on Buenos Aires for the conference to learn and share new findings in aesthetic medicine. Following the congress, Global Stem Cells Group and Estanislao Janowski, M.D., a plastic surgeon specializing in stem cell application in aesthetic and cosmetic medicine will conduct an intensive, hands-on course on stem cell harvesting, isolation and re-integration, to be held April 11. Janowski, a GSCG faculty member and long-time collaborator is the owner and president of Bioplastica, an aesthetic surgical center featuring the latest stem cell applications in cosmetic and anti-aging medicine. This will be the third year Global Stem Cells Group participates in the conference, hosted by the Argentina Society of Aesthetic Medicine (SOARME). A soon-to-be-named GSCG faculty member will also deliver a keynote speech to congress attendees. The international event, which will be held at the Catholic University of Argentina in Buenos Aires, will feature acclaimed stem cell aesthetic practitioners from Argentina and the U.S. SOAME is a member of the Argentine Medical Association (A.M.A.) and of the … Continue reading →
