Mast cells play a key role in the inflammatory process. When activated, a mast cell can either selectively release (piecemeal degranulation) or rapidly release (anaphylactic degranulation) mediators, or compounds that induce inflammation, from storage granules into the local microenvironment.
The authors suggest that the role mast cells play may be more complex than other writers have appreciated; the effect of mast cells on tumors varies, perhaps with tumor types. In some tumors, mast cells encourage growth, angiogenesis, and metastasis; in other tumor types, mast cells limit tumor growth by killing tumor cells.
