Cells expressing GFP-actin are observed as they were chemotaxing towards a micropipette filled with cAMP. The tip of the pipette is moved into different positions as indicated. Images were captured every 18 seconds. From K. Barisic, M. Ecke, C. Heizer, M. Maniak, M. Westphal, R. Albrecht, G. Gerisch, Max-Planck-Institut fur Biochemie, Martinsried, Germany.
