A mast cell is part of a group of cells called leucocytes. Leucocytes are white blood cells and are found in the blood plasma with erythrocytes, red blood cells. Mast cells have immunological functions, or they are part of the immune system. They form part of an early warning system.
We still have a lot to learn about the origins of mast cells (or mastocyte), but it is generally accepted that they are the offspring of stem cells found in the bone marrow, and that mast cells start out life as mast cell 'precursor' cells.
