Figure 2. TVEs and invaginations on neutrophil bodies. Scanning electron images of neutrophils plated onto fibronectin in the presence of the actin-disrupting agent cytochalasin D (10 µg/ml) for 20 (A) and 40 (B) min. TVEs and specific invaginations were observed on the cell body. (B) The invaginations on the neutrophil bodies resemble “porosomes” of exocrine and neuroendocrine cells, with two depressions.
