Dynamics of Erythrocyte Aquaporin Pool Formation in Postnatal Ontogenesis of Mature and Immature Newborn Animals

Abstract

The formation of the rheological properties of erythrocytes in ontogenesis of mature newborn (rats) and immature newborn (guinea pigs) animals was studied in an artificially created model environment using osmotic gradient ektacytometry. A phase change in the deformation properties of erythrocytes in early postnatal ontogenesis of the animals has been shown. An increase in the water permeability capacity of red blood cell membranes occurs during the process of maturation in rats. In contrast, a decrease in this ability was observed in guinea pigs.
