Digitized wild-type cell in chemotaxis
|
Three dimensional direct image reconstruction of a D. discoideum
amobae crawling in a gradient of cAMP. The chemoattractant source is left of the
field. From D. Wessel and D. Soll, Unv. of Iowa |
Digitized clathrin heavy chain null cell in chemotaxis
|
Three dimensional direct image reconstruction of a clathrin heavy chain null Dictyostelium
cell. Note the aberrant cell shape, lack of polarity and numerous fragmented
pseudopods. From D. Wessel and D. Soll, Univ. of Iowa.

Random Motility
|
D. discoideum cells expressing GFP-tagged to a highly conserved actin
binding domain (ABD) crawling on a glass surface. DIC and fluorescence images
were collected simultaneously. Images were captured every 10 seconds.
From K.M. Pang, E. Lee, and K.A. Knecht, University of Connecticut. |
Side view of moving cell
|
Side view of amoebae expressing GFP-ABD plated on a glass surface. DIC and
fluorescence images were collected simultaneously every 10 seconds by confocal
microscopy. From E. Shelden and D.A. Knecht, University of Connecticut.
