A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The ...

CRISPR gene therapy Casgevy can nearly eliminate sickle cell crises, but difficult stem‑cell collection is delaying access ...

A single infusion of stem cells helped frail older adults walk significantly farther.

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Researchers use single-cell analysis to show how transplanted neural stem cells interact with the retina to preserve vision in retinitis pigmentosa.

Getting old doesn't have to mean getting frail. A landmark trial suggests stem cells can reverse the physical decline of ageing ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

A new study from WashU Medicine identifies a previously unknown way that cells purge waste in a process that helps them revert to a stem cell-like state to promote healing after injury. Here, three ...

A Phase I clinical trial published in The Lancet has shown that combining stem cell therapy with standard fetal surgery ...
