Blood stem cell longevity explained

(Medical Xpress)—The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. ...

Uncovering secrets of bone marrow cells and how they differentiate

Bone marrow contains biological factories, which pump out billions of new blood cells daily. The non-blood cells that maintain this production also have the potential to produce bone, fat and cartilage. This output all starts ...

The mechanism behind the pluripotency-differentiation transition

Induced pluripotent stem cells can turn into any type of cell in the body or remain in their original form. In the current edition of Molecular Cell, scientists from the Helmholtz Zentrum München describe how cells decide ...

Process makes stem-cell-derived heart cells light up

A faster, more cost-efficient, and more accurate method of examining the effectiveness of human pluripotent stem-cell-derived cardiac muscle cells has been discovered, according to researchers from Penn State.

Cellular changes lead to chronic allergic inflammation in the sinus

Chronic rhinosinusitis is distinct from your average case of seasonal allergies. It causes the sinuses to become inflamed and swollen for months to years at a time, leading to difficulty breathing and other symptoms that ...

A repurposed drug could open door to more stem cell transplants

A medication used to treat joint and skin conditions might also help people whose only hope of surviving cancer is receiving stem cells from a donor, according to research by a University of British Columbia scientist.
