Mitosis Movie Series: 5. Meeting in the Middle before Parting: Anaphase Lagging
Daniela Cimini, Lisa A Cameron, Edward D Salmon
Mitotic PtK1 cell microinjected with X-rhodamine-labeled tubulin and Alexa 488-labeled CENP-F antibodies to fluorescently label kinetochore fibers (red) and kinetochores/spindle poles (green), respectively....

Daniela Cimini, Lisa A Cameron, Edward D Salmon
Metaphase PtK1 cell microinjected with X-rhodamine-labeled tubulin and Alexa 488-labeled CENP-F antibodies to fluorescently label kinetochore fibers (red) and kinetochores/spindle poles (green), respectively....

Meiosis in a Living Crane Fly Spermatocyte: Meiosis I Time Lapse Movie
James LaFountain Jr, Rudolf Oldenbourg
The events of meiosis I in a living spermatocyte obtained from the testis of a crane-fly larva are recorded in this time-lapse sequence beginning at diakinesis through telophase to the near completion...
10.
Meiosis in a Living Crane Fly Spermatocyte: Meiosis II Time Lapse Movie
James LaFountain Jr, Rudolf Oldenbourg
The events of meiosis II in two living spermatocytes obtained from the testis of a crane-fly larva are viewed in polarized light and recorded in this time-lapse sequence beginning at prophase II through...

Back in Mitosis
Tamara Potapova, Gary Gorbsky (Oklahoma Medical Research Foundation, Oklahoma City, OK)
This video shows a Xenopus laevis S3 cell reversing cytokinesis and exit from mitosis. The cell is stably expressing GFP alpha-tubulin to visualize dynamics of the microtubule network. This cell was blocked...

Back in Mitosis: Waltz of the Microtubules
Tamara Potapova, Gary Gorbsky (Oklahoma Medical Research Foundation, Oklahoma City, OK)
This video shows the microtubule network of a Xenopus laevis S3 cell during induction and reversal of mitotic exit. This cell, stably expressing GFP alpha-tubulin, was blocked at metaphase with high levels...

Terminal Stage of Meiosis I Prophase (Diakinesis) in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
When viewed with polarized light, birefringent microtubules of the asters appear with bright contrast on the dark, non-birefringent ground cytoplasm. Here the two asters are positioned on opposite sides...
16.
Transition from the Terminal Stage of Meiosis I Prophase (Diakinesis) to Prometaphase I in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
As the nuclear envelope disintegrates at the prophase-prometaphase transition, birefringent microtubules appearing with bright contrast originate from the two dark-contrasted centrosomes and penetrate...

Prometaphase of Meiosis I in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
This image was made about 20 minutes following disintegration of the nuclear envelope, the event that marks the transition from prophase to prometaphase. Here, as the spindle is being assembled, the kinetochore...

Metaphase of Meiosis I in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
In this image, made just prior to the onset of anaphase, the kinetochore fibers that connect the fully congressed bivalent chromosomes to the spindle poles stand out with exceptionally bright contrast....
19.
Anaphase of Meiosis I in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
This image was made at about 5 minutes after the onset of anaphase. The image is a snapshot of an early time point of anaphase - the phase of meiosis I during which disjoined half-bivalents are segregated...
20.
Telophase of Meiosis I in a Living Crane Fly Spermatocyte
James LaFountain Jr, Rudolf Oldenbourg
This image was made about 20 minutes after the onset of anaphase. Note that the autosomes that initiated anaphase have reached the poles, and their kinetochore fibers have essentially shortened completely....
