<P> A mast cell ( also known as a mastocyte or a labrocyte ) is a type of white blood cell . Specifically , it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems 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 , angiogenesis , immune tolerance , defense against pathogens , and blood -- brain barrier function . </P>
