In connection with the increase in the incidence of respiratory organs, interest has revived in the study of fundamental issues related to the diversity of lung cells. The aim of the study was to determine the features of the structural organization of the APUD-systcm of human lungs at different stages of embryonic development, as well as in inflammatory and tumor processes in them. The lungs of human fetuses and newborns, as well as children who died from respiratory diseases and in cancer patients were studied by histological methods. After fixation in Bouin's fluid, paraffin sections were stained using general histological methods: hematoxylin and cosin, according to the Van Gicson and Weigert method. To identify argyrophilic neuroendocrine cells, the sections were impregnated with silver nitrate according to the Grimclius method. Neuroendocrine cells (apudocytes) of the lungs arc determined at the tubular and alveolar stages of organ histogenesis. Branching of the bronchial tree is predetermined by closed apudocytes and neuroepithelial bodies. After birth, their number decreases. With maladaptive remodeling of the lungs caused by inflammation and especially by the tumor process, proliferation of apudocytes of a predominantly closed type occurs, and neuroepithelial bodies are also formed.
