A newly discovered pair of stem cell lineages drives the formation of both tooth roots and the bone that anchors them. Understanding how these cells switch roles could pave the way for regenerating ...

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

A study shows that high levels of negatively charged lipids can lock growth receptors into an overactive state, driving ...

The research group of Prof. Sanjiv Luther at the Department of Immunobiology of the University of Lausanne has discovered ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

Cancer cells can disarm the immune system not just by hiding from it, but by actively reprogramming nearby immune cells into ...

Researchers have identified an unexpected mechanism that links age-related stress to the decline of blood-forming stem cells.

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...
