Abstract:
By electron microscopic observation,we found few pit cells in liver,spleen.lungs,and small intestine in Wistar rat.The pit cells show several morphologicalcharacteristics as follows:1.electron dense granules in cytoplasm,which aresurrounded by a limiting membrane;2.vesicles with rod shaped bodies incytoplasm;3.eccentric nucleus with marginal heterochromatin;4.well developedpseudopodia.In addition,the pit cells have also been found in breast carcinoma in3 patients.According to their distribution and morphology,we preliminarilydeduced they probably belong to natural killer cells and may act as a cytotoxicagent and an immunological defender against carcinoma.
