Amniotic stem cellsAmniotic stem cells are the mixture of stem cells that can be obtained from the amniotic fluid as well as the amniotic membrane. They can develop into various tissue types including skin, cartilage, cardiac tissue, nerves, muscle, and bone. The cells also have potential medical applications, especially in organ regeneration. The stem cells are usually extracted from the amniotic sac by amniocentesis which occurs without harming the embryos.
Trisomie 13La trisomie 13 résulte de la présence d’un chromosome 13 supplémentaire. La formule chromosomique des patients est donc de 47 chromosomes au lieu des 46 chromosomes de l’espèce humaine. Klaus Patau est le premier à décrire en 1960 la trisomie 13. Si la trisomie 13 est la plus rare des trisomies viables, c'est aussi l'anomalie chromosomique la plus fréquente qui soit caractérisée par des malformations multiples et qui laisse peu d'espoir de survie après son diagnostic. Cette pathologie atteint de très nombreux organes.
Rh diseaseRh disease (also known as rhesus isoimmunization, Rh (D) disease, and blue baby disease) is a type of hemolytic disease of the fetus and newborn (HDFN). HDFN due to anti-D antibodies is the proper and currently used name for this disease as the Rh blood group system actually has more than 50 antigens and not only the D-antigen. The term "Rh Disease" is commonly used to refer to HDFN due to anti-D antibodies, and prior to the discovery of anti-Rho(D) immune globulin, it was the most common type of HDFN.
