Placental Evolution within the Supraordinal Clades of Eutheria with the Perspective of Alternative Animal Models for Human Placentation

摘要: Here a survey of placental evolution is conducted. Placentation key factor for the mammals that had evolved an astonishing diversity. As temporary organ does not allow easy access, it still well understood. The lack data also restriction better understanding development, structure, and function in human. Animal models are essential, because experimental access to human placenta naturally restricted. However, there single ideal model entirely similar humans. It particularly important establish other than mouse, which characterised by short gestation period poorly developed neonates may provide insights only early pregnancy. In conclusion, current evolutionary studies have contributed essentially providing pool recent future approaches meet requirements long advanced developmental status newborn Suitability limitations taxa as alternative animal discussed. further investigations especially wildlife should be conducted order learn more about full plasticity system.
