Mast Cell Interaction with Neutrophils in Human Gastric Carcinomas: Ultrastructural Observations

Figure 2

Mast cell showing a full complement of granules is in contact with a neutrophil, characterized by early apoptotic changes ((a), ×4000); another example of aggregation between mast cells and apoptotic neutrophils in the tumor stroma of a gastric adenocarcinoma ((b), ×4000); mast cell established pointed or flat areas of membrane contact with a neutrophil showing early apoptotic changes. Mast cell exhibits cytoplasmic microtubules, some of which are in close vicinity to granules ((c), ×10000); neutrophil satellitosis around mast cell showing peripheral location of granules and cytoplasmic microtubules. Some neutrophils show early apoptotic changes ((d), ×6000).
