γ-Tubulin localizes at cell–cell boundaries. (A and B) Immunostaining of anti–γ-tubulin in fixed wild-type embryos (left), costained with DAPI to visualize nuclei (middle), and merged (right). Dorsal view, anterior is to the left. (A) During nuclear migration, γ-tubulin localizes to hyp7 cell–cell boundaries. (B) In earlier embryos, γ-tubulin localizes primarily to centrosomes. Bar, 10 µm.
