The time lapse movie spans fertilization, ooplasmic segregation, and early divisions in the egg of the tunicate Phalusia mammilata. Contrast is provided by both polarizing microscopy and differential...

The events of meiosis I in a living insect spermatocyte beginning at metaphase with bivalents at the spindle equator, followed by anaphase onset, chromosome segregation and the start of cytokinesis. T...

Movie of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for...

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...

The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge...

Time lapse movie showing several sequences of mitosis in pollen mother cells of the Easter Lily recorded in 1951 on 16 mm film with an early polarizing microscope developed by Shinya Inoue. The work w...

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

The time lapse movie shows the rocking motion of the spindle that appears to play a role in the unequal cleavage divisions in a fertilized Spisula solidissima (Clam) egg. Eventually, this leads to t...

The events of meiosis II in a living insect spermatocyte beginning at the completion of prophase II through the comletion of cytokinesis. Testes from the Crane fly Nephrotoma suturalis were observed w...

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...
