Fig. 1. Confocal microscopy images showing the differences in the organisation and dynamic properties of the actin cytoskeleton in B1 and C3 cells. Response of cells to (A)10 minutes stimulation with 20 mM glucose after 0 mM glucose; (B) 16.7 mM after 2.8 mM glucose; and (C) 1 mM IBMX without glucose. F-actin was stained with phalloidin. Bars, 10 µm.
