Some blood stem cells are better than others

In your body, blood stem cells produce approximately 10 billion new white blood cells, which are also known as immune cells, each and every day. Even more remarkably, if some of these blood stem cells fail to do their part, then other blood stem cells pick up their slack and overproduce whichever specific type of

The accidental discovery of stem cells

Till knows of what he speaks; it was almost 60 years ago that the renowned University of Saskatchewan graduate, along with a colleague, found something unexpected in research results that simply could not be ignored. Although they did not know it at the time, the two scientists were on the path to discovering stem cells

How bone marrow niches keep stem cells thriving

Hematopoietic stem cells (HSCs) are a class of stem cells located in bone marrow. HSCs give rise to every type of blood cell—from the red blood cells that carry oxygen to the white blood cells of the immune system. Bone marrow provides a niche that both houses and regulates HSCs to ensure proper formation of
