Fig. 3. The organization of microtubules in 185/333⁺ cells is distinct. Merged confocal images show the localization of 185/333 proteins (red) and microtubules (green) in coelomocytes. The 185/333⁺ cells have an unusual pattern of microtubule bundles that are associated with filopodia (A) and cytoplasm (B) that contrasts with the perinuclear microtubules seen in type 1 (discoidal) cells (labeled 1) and the extensive cytoplasmic array of single microtubules present in type 2 (polygonal) cells (labeled 2).
