Figures 197 (upper) and 198 (lower) from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. show electron microscopic views of the Golgi complex. Upper panel: A thin section pr...

This light micrograph shows the outside edge of two seminiferous tubules of a mouse testis. This section is a 1um thick transverse section, stained with toluidine blue to highlight the cells, with the...

The image shows a developing Drosophila spermatid immunostained for caspase activity (green). TRITC-phalloidin is used to label actin (red). Caspase is required in spermiogenesis for the elimination ...

The time-lapse movie made in 1974 shows meiosis in spermatocytes of Chrysochraon japonicas (grasshopper) as seen with the polarizing microscope. The principal birefringent components are the spindle m...

Transmission electron micrograph of a cross section through the nucleolus from a Chinese hamster spermatogonium revealing a complex distribution of regions of varying granular textures.

Transmission electron micrographs showing chromosomes in dividing spermatogonia during metaphase in tissue from ram testis (upper panel) and as they begin to separate during early anaphase in tissue f...

Time series of meiosis I, starting at metaphase, in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Time-lapse polarization microscopy using a Nik...
