Time lapse movie of meiosis II in spermatocytes of the Locust Psophus stridulus showing telophase and the early spermatid stage. This is a historic movie made in the early 40s by Kurt Michel of the ...

Transmission electron micrograph of surface of nuclear envelope of guinea pig spermatocyte prepared by the Freeze-fracture technique shows the unusual clustering of nuclear pores in these cells. From...

The image shows a mouse spermatocyte in meiosis immuno-labeled for two components, SYCP3 (red) and SYCP1 green) of the synaptonemal complex. The red and green signals have been offset to facilitate vi...

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 353 (upper) and 354 (lower) from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Glycogen deposits tend to accumulate in dense regions, such as shown in thes...

Nephrotoma suturalis spermatocyte (crane fly sperm cell) during metaphase in meiosis. Image was captured using a newly developed orientation-independent differential interference contrast technique. ...

The events of meiosis I in a living insect spermatocyte beginning at diakinesis through telophase to the near completion of cytokinesis. Testes from the Crane fly Nephrotoma suturalis were observed wi...

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...

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...

The events of meiosis I in a living insect spermatocyte beginning at metaphase I with bivalents at the spindle equator followed by anaphase, segregation of half-bivalents diakinesis and commencement o...
