Scanning electron micrograph of a hamster oocyte cumulus complex. Cumulus cells (purple) and matrix (gray) are shown. Small blood clots (red) also often appear in oocyte cumulus complexes. The red blo...

Confocal micrograph of a stimulated mast cell that has just exploded releasing numerous histamine granules. The remains of the cell are seen towards the lower left, still containing a number of granul...

Colorized transmission electron microscope image of a mast cell full of histamine granules (pink). Histamine is released as part of an allergic reaction. The diameter of the cell is approx. 8.4 microm...

Immunoelectron microscopy of mammary gland tissue from lactating rats with medial cisternae of the Golgi apparatus indicated by immunogold labeling of MG-160, a 160 kDa membrane sialoglycoprotein spec...

Immunoelectron microscopy of mammary gland tissue from lactating rats with the trans-Golgi network identified by immunogold labeling of TGN38, a transmembrane trans-golgi protein. Note that trans‐Go...
