Study Notes
Mast Cells
- Origin: UMC (Undifferentiated Mast Cells)
- Characteristics: large cell with granular, dark basophilic cytoplasm and central rounded pale nucleus
- Staining: metachromatic staining with toluidine blue
- Similarity: similar to basophils
- Function: initiate allergy response
- Release: histamine, leukotrienes, and other chemical mediators
- Effects: smooth muscle contraction, vasodilation
Eosinophils
- Origin: B-Cells (lymphocytes)
- Functions: secrete reticulin, support, phagocytic activity, and antigen presentation
- Anticoagulant: heparin secretion
- Chemotactic factor: attraction to specific sites
Macrophages
- Origin: blood monocyte
- Sites: fixed (tissue histiocytes) and free
- Functions: phagocytic activity, antigen presentation, and tissue repair
