  • Title: [Polarization microscopic studies of the fine structure of the maternal-fetal barrier in normal human placentas depending on gestational age].
    Author: Keller F, Scheuner G, Ruckhäberle KE.
    Journal: Gegenbaurs Morphol Jahrb; 1981; 127(5):668-71. PubMed ID: 7343408.
    Abstract:
    The submicroscopic structure of the throphoblast basement membrane and the collagen in the chorionic villi of human placentas was investigated by polarization microscopic technique. The study establishes a quantitatively measurable difference in the submicroscopic range of the placental membrane in relation to histologically classified disturbances of maturity.
