Abstract
Renewed interest in cell shape has been prompted by a recent flood of evidence that indicates that cell polarity is essential for the biology of motile cells. The uropod, a protrusion at the rear of amoeboid motile cells such as leukocytes, exemplifies the importance of morphology in cell motility. Remodelling of cell shape by uropod-interfering agents disturbs cell migration. But even though the mechanisms by which uropods regulate cell migration are beginning to emerge, their functional significance remains enigmatic.
