Fig. 2.

The supernumerary centrosomes induced by a chlamydial infection contain centriole and pericentriolar matrix markers. The centrosome morphology of uninfected or C. trachomatis-infected HeLa (top two panels) and HFF cells (bottom two panels) was examined by immunofluorescence. In the first two columns from the left, centrin2 and C-Nap1, which are markers of the centriole, are shown in green, and the pericentriolar marker, γ-tubulin, is in red. In the remaining columns, the centriole marker, HsSAS-6, and the pericentriolar matrix markers, kendrin and GCP2, are shown in green, and costained with centrin2 in red. The scale bar corresponds to 2 μm.
