Eosinophils bind to breast carcinoma cells. Freshly isolated eosinophils (2 × 10⁶/ml) were added to MDA-MB-435S (A) or BT-20 (B) cells treated with buffer alone or TNF-α as described in Figure 1 ▶ . After 15 minutes, nonadherent and loosely adherent cells were removed and eosinophil adhesion was determined as described in Methods. Data represent the mean ± SEM of at least three experiments. * P < 0.05 as compared to control.
