Time lapse movie of meiosis II in spermatocytes of the Locust Psophus stridulus showing two sequences that include metaphase and anaphase. This is a historic movie made in the early 40s by Kurt Mich...

Figures 201 and 202 from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The Golgi apparatus of nurse cells from the testis of the woodlouse, Oniscus. Image by David Philli...

Movie of meiosis I and II in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse DIC microscopy using a Nikon Microphot SA, equipped for liquid crystal polarized light microscopy...

Movie of meiosis I (diakinesis through telophase)in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Flattening prevents completion of cytokinesis. ...

Movie showing the dynamics of kinetchore microtubules during meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polarization micros...

Movie of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse DIC microscopy using a Nikon Microphot SA, equipped for liquid crystal polarized lig...

How the cell cytoplasm is spatially organized is of fundamental interest. In ordinary animal cells the cytoplasm is organized by a radial array of microtubules, called an aster. Aster microtubules are...

Movie of anaphase B (spindle elongation) of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for liqu...

Time series showing the dynamics of kinetchore microtubules during meiosis II in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polarization...
