Skin cell (keratinocyte)

This normal human skin cell was treated with a growth factor that triggered the formation of specialized protein structures that enable the cell to move. We depend on cell movement for such basic functions as wound healing and launching an immune response. Image courtesy of Torsten Wittmann, University of California, San Francisco. Part of the exhibit Life:Magnified by ASCB and NIGMS.
