Chemotaxis of a Single Cell Towards cAMP

Time-lapse video microscopy (DIC optics, 60X objective) of a single cell (Dictyostelium, I think) moving toward a micropipette containing the chemoattractant cAMP. Note that the cell changes direction in response to movement of the micropipette by extending a new pseudopod in the direction of the pipette tip.
