Fig. 1. SBF-SEM of mitotic spindles.

Fig. 1

(A) Practical workflow. A single mitotic cell on a gridded dish is first visualized by light microscopy (left) to assess its mitotic stage and transfection status. The cell is then fixed, processed and embedded for SBF-SEM. A series of SEM images are captured at 60 nm intervals through the block. Using Amira, the MTs are segmented along with any other cellular features. Analysis of segmentation data is carried out in Igor Pro or R. (B) A single SBF-SEM image is shown together with a 4× magnification and detail of segmented MTs (green). (C) 3D rendering of MTs in the mitotic spindle is shown with an orthoslice at three different depths (left to right), as en face (upper row) or tilted views (lower row).
