Microtubule and cytokeratin filament systems are still present after plakoglobin depletion. (A–D) The microtubule (A and B) and cytokeratin (C and D) arrays in either uninjected (A and C), or plakoglobin depleted (B and D) blastulae. Microtubules are shown in the cells lining the roof of the blastocoel, whereas cytokeratin filaments are shown in the surface layer of animal cells. No significant differences were found after plakoglobin depletion.
