Cells without functional lamellipodia are still highly motile but lose their ability to stay on track, report researchers at the Stowers Institute for Medical Research in the April 9, 2012, online issue of the Journal of Cell Biology. Their study provides new insight into cell motility, a complex and integrated process, which, when...
