While extracellular signals can be captured with less invasive methods, they do not provide much detail about the cell's electrical activity. "It is like listening to a conversation through a wall–you ...

This graphic illustrates paracrine adhesion signaling on small extracellular vesicles, which secretes a protein called galectin-3, which promotes endocytosis so the vesicle can be absorbed into the ...

As a grad student in cell biology, Shaeri Mukherjee was always on the lookout for new ways to fiddle with cells’ internal structures. It was the early 2000s, and Mukherjee was working in Dennis ...

Hematopoietic stem cells give rise to all blood cells in the body. Most of the time they are not dividing. Rather, they serve as a reserve for the times when the body needs rapid blood formation. “One ...

Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the ...

When exposed to stressful conditions, several proteins tend to misfold and form aggregates inside or outside cells. These aggregates, if accumulated, may contribute to age-related disorders, including ...
