How Complex Cells Sense the Chemical Trails

Amoebas aren't the only cells that crawl: In animals, movement is crucial to development, wound healing and immune response, not to mention cancer metastasis. In two new studies from Johns Hopkins, researchers answer long-standing questions about how complex cells sense the chemical trails that show them where to go - and the role of cells' internal "skeleton" in responding to those cues. In following these chemical trails, cells steer based on minute ...
