The questions of how the nutrition status of the gut controls stem cell division and differentiation, and how the nutrient adaptation of stem cells changes as during ageing have not been ...

Recently, a new phenomenon related to stem cell aging was observed in a study at the Sanford Stem Cell Research Institute in ...

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell ...

Dr. Jason Chien was not happy with the answers he could give his patients. Chien, an investigator in the Clinical Research Division's Pulmonary/Critical Care Section at the Hutchinson Center, knew ...

Mitochondria are remarkable shape-shifting organelles that have long been understood as the powerhouses inside our cells. But relatively little is known about how the constant fission and fusion of ...

Changes in tissue structure are nearly universal in aging animals. Such structural changes are evident at the microscopic and macroscopic levels and are almost invariably accompanied by impairment in ...

Researchers have transplanted precursor stem cells into the damaged heart muscle of pigs, repairing injured cells and improving heart function. The study may lead to a treatment that can regenerate ...

Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study. Biologists found fasting dramatically improves stem cells' ability to regenerate, in both aged ...

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal ...
