It’s a last resort treatment for...
by Julia Evangelou Strait, Washington University School of Medicine Studying mice, researchers at Washington University School of Medicine in St. Louis have developed a method of stem cell transplantation that does not require radiation or chemotherapy. Above, the right panel shows mouse bone marrow after the debilitating effects of radiation followed by an infusion of donor...
This open access paper reviews the relationship between DNA damage and inflammation in the specialized environments that support stem cell populations. Aging produces many changes that lead to reduced stem cell function. Changes in the niche, the supporting cells that help to ensure stem cells retain their function, are of increasing interest to the research community. The chronic inflammation of aging is also an area...

The findings provide new insight into how hair and tissues age....
By Gina Kolata By observing mouse hair follicles, scientists discovered an unexpected mechanism of aging. “If I didn’t see it with my own eyes I wouldn’t believe it,” one said. Researchers have found that hair loss from aging results from stem cells escaping hair follicles.Credit…Alamy Every person, every mouse, every dog, has one unmistakable sign of...

GUT MICROBIOTA INDICATED DYSBIOSIS BEFORE HCT; HOWEVER, IT WAS IMPROVED TO RESEMBLE THAT OF THE HEALTHY FAMILY MEMBERS AFTER HCT. THIS STUDY REVEALED THAT HCT HAS A FAVORABLE OUTCOME FOR XIAP DEFICIENCY....
“What do you want to be when you grow up?” is a question it seems like every child gets asked. A few precocious ones might answer “a doctor” or “an astronaut,” but most will probably smile and shrug their shoulders. But well before a child could comprehend the question or the concept of choosing one’s...
by Hokkaido University In mice large intestine, the goblet cells (blue) are significantly reduced in number after allogeneic bone marrow transplantation (right), comparing to a control syngeneic recipients (left). Allogeneic stem cell transplantation can cause a loss of protective goblet cells from the colon’s inner lining, which can be fatal. But boosting those cells beforehand...
by University of North Texas Health Science Center When news of the coronavirus emerged from Wuhan, China, Kunlin Jin, Ph.D., and a team of international researchers quickly joined forces to fight the mysterious disease. Dr. Jin relied on his more than 20 years of knowledge about stem cells to work with an international team driven...
