Summary The intestinal absorption of equine ferritin was studied in newborn rats and rabbits by means of electron microscopy and immunological tests. The absorption of ferritin begins by invagination of the plasma membrane, which forms vesicles and vacuoles in the brush border region. The ferritin moves downwards into the great supranuclear vacuole and then is taken up by the Golgi complex. The protein travels freely through the neighbouring cytoplasm and arrives into the dilated intercellular space. After passing through the basal membrane, the ferritin penetrates into the vessels. The intracellular course of ferritin is the same in both species and corresponds to that of other substances such as lipids. On the contrary, the immunological demonstration of this protein in peripheral blood is possible only in newborn rats; in young rabbits it disappears immediately after its arrival in the circulation.
