Evidence of the heterogeneity of mast cell population based on their biogenic amine content.
The heterogeneity of the mast cells localized in various organs has been demonstrated by histochemical determination in their indole amine and histamine content. The strongest amine reaction was found in the mast cells in the mesenterium and peritoneal fluid where their maturation occurs. The reaction of the subcutaneous connective tissue is weaker; in the thyroid gland the reaction is weak as well as diffuse. In the thymus the mast cells localized along the vessels give a strong histamine reaction. The experiments support previously published data concerning the heterogeneity of mast cell populations.
