Messages from the placentae across multiple species: A 50 years exploration.

This review explores eight aspects of placentation in multiple mammalian. 1) Specialities of gestational trophoblastic disease. 2) Clinical significance of single umbilical artery (SUA) syndrome. 3) Pulmonary trophoblast embolism in pregnant chinchillas and DIC in pregnant giant panda. 4) Genetics status and placental behaviors during Japanese serow and related antelopes. 5) Specific living style and placentation of the Sloth and Proboscis monkey. 6) Similarities of placental structures between human and great apes. 7) Similarities of placental forms in elephants, manatees and rock hyrax with different living styles. 8) Specialities of placental pathology in Himalayan mountain people.

CONCLUSIONS

It was taught that every mammalian species held on placental forms applied to different environmental life for their infants, even though their gestational lengths were different.
