Fig. 3From: Ultrastructural analysis of mitotic Drosophila S2 cells identifies distinctive microtubule and intracellular membrane behaviorsExamples of metaphase S2 cells. Note (a) the stacks of parallel endoplasmic reticulum membranes and (b) the kinetochores with k-fibers (arrowheads). Asterisks indicate the cell regions shown at higher magnification in the images on the right. Scale bars: left images, 5 μm; right images, 1 μmBack to article page
