In a study of the immune systems of mice, scientists at Johns Hopkins Medicine say they have found a new role for a protein, ...

We are studying several genes involved in different aspects of stem cell activation, including some that transduce initial signals, and others that regulate self-renewal and differentiation. This work ...

Endothelial cells are also likely to participate in activation, both by production of cellular fibronectin and via conversion of transforming growth factor (TGF)-beta from the latent to active ...

Damage to the mitochondria, the 'power plants' of the cells, contributes to many diseases. Researchers now describe how cells with defective mitochondria activate a special recycling system to ...

Past research has shown that when hair follicle stem cells are stressed by hair shaft loss or shrinking follicles, they can ...

although these stem cells may be harder to activate and expand if they have already been exposed to chemotherapies and/or radiation treatments. Similarly, some gene therapies, especially for blood ...

Contrary to what you likely learned in school, ferrying oxygen isn’t the only function of red blood cells. In a study published today (October 20) in Science Translational Medicine, researchers show ...
