Nucleoside phosphatases of fetal and maternal blood cells: electron microscope study
Science (New York, N.Y.)
|October 22, 1965
Surface membranes of the blood cells located within the maternal blood sinuses of the rat placenta contain reaction products of nucleoside phosphatases. Fetal blood cells separated from maternal blood by the placental labyrinth show no activity during normal or prolonged gestation. Neonatal blood cells examined 34 hours after parturition show these enzyme activities.
