The appearance of alveolar macrophages in human fetuses' and animals' lungs coincides in time with the initiation of differentiation of the alveolar epithelium cells into the 1st- and 2d-type alveolocytes and with the beginning of an active functioning of the latter as well. The number of fetal lung alveolar macrophages tends to increase with lengthening of the gestation period, their cell pool becoming heterogeneous, which fact implies that the above pool will include that sort of cells being endowed with a varying degree of functional activity.
