WebDec 8, 2024 · Figure: A brief overview of mast cell functions and characteristic proteins and molecules. Markers for mast cell maturation. Mast cells originate from hematopoietic stem cells in the bone marrow before entering the blood as mast cell precursors (MCp). MCp will then mature within peripheral tissues in a highly regulated process. WebMast cells also are important for defense against parasites. Mast cells are found in tissues and can mediate allergic reactions by releasing inflammatory chemicals like histamine. Monocytes, which develop into macrophages, also patrol and respond to problems. They are found in the bloodstream and in tissues.
