Modulation of tryptase secretion from human colon mast cells by histamine

Figure 1 Histamine, anti-IgE and calcium ionophore (CI) in-duced tryptase release from colon mast cells. The values shown are mean ± SEM for six separate experiments. Stimulus or HBSS alone was incubated with cells for 15 min before termination of the reactions. ^aP < 0.05 compared with spontaneous release group (paired Student’s t test).
