stem cells

In mammalian adult brains, neural stem cells are only present in few specific regions, so-called niches. Only these niches are capable of generating new neurons. For the first time, researchers have defined the proteome of these niches, the entire set of expressed proteins, and compared it to other regions of the brain. The findings[1] help… Read more

It’s the promise of stem cell medicine: Someday soon, clinics will rebuild diseased or broken hearts, kidneys, pancreases or blood by growing and reprogramming human cells, then adding them back to the bodies of the patients they came from. If only it were that easy. After two decades of human stem cell research, researchers have… Read more

A type of cell that may be able to regenerate liver tissue has been identified by King’s College London researchers. Treating liver failure without the need for transplants could be a potential application. The scientists have identified a new type of cell called a hepatobiliary hybrid progenitor (HHyP), that forms during our early development in… Read more

Electronic cigarettes, often targeted to youth and pregnant women, cause a stress response in neural stem cells, critical cells in the brain, reports a research team at the University of California, Riverside. Using cultured mouse neural stem cells, the UC Riverside researchers identified the mechanism underlying electronic cigarette-induced stem cell toxicity as “stress-induced mitochondrial hyperfusion,”… Read more

Stem cells derived from the placenta known as Cdx2 cells can regenerate healthy heart cells after heart attacks in animal models, new research from Icahn School of Medicine at Mount Sinai has shown. The findings may represent a novel treatment for regenerating the heart and other organs. “Cdx2 cells have historically been thought to only… Read more
