A mast cell (also known as a mastocyte or a labrocyte[1]) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.

Mast cells are immune cells that migrate from blood into connective tissue. They engage in inflammatory responses by releasing molecules that dilate blood vessels and recruit other cells.

Mast Cells Definition: A "mast cell is a connective tissue-resident cell, which is also regarded as a mastocyte or a labrocyte, that includes several histamine and heparin-rich granules. It's a kind of granulocyte that comes from a myeloid stem cell and is used in the immune and neuroimmune systems. In 1877, Paul Ehrlich invented mast cell meaning.
