Internal compass points cells towards injury

Posted on 6 Apr 2013 in Featured, Health, Journalism

Cells can’t see or hear, but some of them have a sense we lack: they can detect the electric fields generated by a wound. Identifying how they do this could help efforts to boost wound healing. The flow of ions across a cell membrane creates tiny electric fields. Tissue damage changes that field, and cells involved in tissue repair seem to sense this change. Image: Calsidyrose
