Induction of tryptase and histamine release from human colon mast cells by IgE dependent or independent mechanisms

Figure 1 Anti-IgE and calcium ionophore induced histamine re-lease from colon mast cells. The values shown are mean ± SEM for four 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).
