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 ...

Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like ...

Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...
