[The quantitative characteristics of the fibroblastic series of cells in the tunica submucosa of the human bronchi].
Quantity of cells of fibroblastic cells in the wall of human bronchi was studied in age aspect. The quantity of these cells in tunica submucosa of the bronchi belongs to different generations, in juvenile age approaching the level of the adults. In senile age numeral density of cells is less than that in infancy. Changes of cell numbers in all the age groups studied are more expressed in large bronchi. Numerical density of the cells of fibroblastic series in tunica submucosa of bronchial walls correlates with their diameter. In sites of bronchi branching into further generations numeral density of cells of fibroblastic series increases, which is, probably, connected with mechanical impact of the air flow on bronchial walls in these regions.
