Spreading Cells 01

3328

Cells move forward with lamellipodia and filopodia supported by networks and bundles of actin filaments. Proper, controlled cell movement is a complex process. Rong Li and Praveen Suraneni, Stowers Institute for Medical Research View Media

Leading cells with light

2708

A blue laser beam turns on a protein that helps this human cancer cell move. Responding to the stimulus, the protein, called Rac1, first creates ruffles at the edge of the cell. Yi Wu, University of North Carolina View Media
