Fig. 18-19. 9-day specimen of Horizon Vb

18 Note early predecidual reactions with infiltrating leucocytes about the ovum. Early utero-placental circulation is visible in the form of an empty maternal blood space at right communicating with the coalescing lacunae of the future intervillous space. Carnegie Embryo 8171, Section 3-2-11. X 100.

19 The significant feature of this gross implantation site is its inconspicuous nature due to small size of ovum and lack of endomctrial ulceration or congestion. Carnegie Embryo 8171, Sequence 3. X 22.

Three 9-day specimens of Horizon Vb, characterized by syncytiotrophoblastic lacunae with early utero-placental circulation, amniogenesis, a simple bilaminar germ disc and only variable degrees of exocoelomie (Heuser’s) membrane formation.
