The present article gives an overview of . The significant diversity in MC development and tissue-specific functional characteristics has recently begun to be understood.Lineage-specific differentiation of human induced pluripotent stem cells (hiPSCs) relies on complex interactions between biochemical and physical cues.Human mast cells are broadly grouped into three categories based on the types of proteases released upon degranulation: tryptase-positive mast cells (MCT) which secrete tryptases, chymase-positive mast cells (MCC) which secrete chymases, and tryptase-chymase-positive mast cells (MCTC) which secrete both. They’re made in your bone marrow, then move through your bloodstream into your tissues.Efforts to gain insight into the biochemical events occurring during immunological activation of mast cells and basophils could lead to the identification of new biochemical targets for therapeutic interventions in several immunological disorders.
On light microscopy, using special stains like toluidine blue and Giemsa, MCs can be appreciated as large cells with a diameter varying from 5–15 μm exhibiting heterogeneity in shape from round or oval to spindle shaped.
