Scanning electron micrograph of the surface of a peritoneal mast cell from mouse shows undulating folds, and few microvilli. The membrane folds could be misinterpreted for microvilli if analyzed in t...

Cells from peritoneal cavity exudate of the mouse, exposed to sodium azide at 22°C for 22 minutes. The macrophage in the field of view has extended long microvilli, showing a rapid response to change...

Rapid extension of microvilli on the surface of a peritoneal macrophage, induced by treatment with a metabolic inhibitor, sodium azide, after 20 minutes at 22° C. Microvilli on neighboring lymphocyt...

This image shows two different types of white blood cells from a mouse which are essential for mammalian immune response to protect from infection. The larger cell is a macrophage and the smaller two...
