Cells ‘vomit’ waste to promote healing, mouse study reveals (IMAGE)
Caption
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 mouse stomach cells (numbered) are shown jettisoning cellular debris through cavities (white) that form in their membranes. The researchers dubbed the new purging process “cathartocytosis,” combining Greek root words meaning cellular cleansing.
