Fig. 3. Control cells (A,D) and cells incubated with 1 µmol l1
PTX-6 (B) or 5 nmol l1 MTX (E) for 4 h. Confocal microscopy
showed that both marine toxins affect the microfilament network without
modifying the morphological pattern of isolated intestinal cells. (C,D)
Transmission images of cells incubated with the toxins.
