This study was designed to determine the presence of cell-bound histamine and mast cells, if any, in the lung and skin of nonhuman primate fetuses and neonates. The results indicate that cell-bound histamine can be detected in both tissues of the rhesus monkey fetus by 60 days of gestation, the earliest age examined, at levels that are 2% to 3% of levels present in yearling animals. Levels increase markedly during the last life mo of gestation; however, at birth, levels are only 12% to 46% of those observed in the yearling and are lower than levels observed at 150 days of gestation. Mast cell numbers in lung and skin of the fetus closely parallel histamine content.
