A mast cell (also known as mastocyte and labrocyte) is a resident cell of several types of tissues and contains many granules rich in histamine and heparin. Although best known for their role in allergy and anaphylaxis, mast cells play an important protective role as well, being intimately involved in wound healing and defense against pathogens.

Famous quotes containing the words cell and/or mast:
“In America all too few blows are struck into flesh. We kill the spirit here, we are experts at that. We use psychic bullets and kill each other cell by cell.”
—Norman Mailer (b. 1923)
“What do we plant when we plant the tree?
We plant the ship that will cross the sea,
We plant the mast to carry the sails,
We plant the planks to withstand the gales
The keel, the keelson, and beam and knee
We plant the ship when we plant the tree.”
—Henry Abbey (18421911)
