Graphic: cells moving through the body [28/10/2014] Amoebas aren't the only cells that crawl: Movement is crucial to development, wound healing and immune response in animals, 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.How cells know which way to go - Read more
