Telophase! Image of the Week - December 4, 2017  CIL:198 - http://www.cellimagelibrary.org/images/198  Lily mitosis. A light microscope image of a cell from the endosperm of an African globe lily Haemanthus (Scadoxus) katherinae. This is one frame of a sequence that shows all phases of mitosis. The lily is considered a good organism for studying cell division because its endosperm has a liquid phase and chromosomes are thick and easier to see than human ones.  Andrew S. Bajer  Public Domain

Metaphase! Image of the Week - November 13, 2017  CIL:44601 - http://www.cellimagelibrary.org/images/44601  Shown is a mitotic PtK2 cell at metaphase immunostained for microtubules (red) and kinetochores (green) with DNA stained blue. The image was obtained using structured illumination microscopy (SIM, Deltavision OMX system) which provides 'super-resolution' beyond the diffraction limit set by the wavelength of the illuminating light.

Image of the Week - November 20, 2017  CIL:39037 - http://www.cellimagelibrary.org/images/39037  An anoptral contrast micrograph of a planktonic freshwater rotifer. The rotifer are microscopic but complex animals (mostly less than 1mm long) found in wet habitats. They are important members of the freshwater plankton of lakes. The sexes are separate but males are often rare or even unknown.   Spike Walker  CC BY-NC-ND 2.0 UK
