Amniocentesis:
Fetal lung development can be tested by sampling the amount of surfactant in the amniotic fluid in pregnancies greater than 30 weeks. An emerging indication for amniocentesis is in the management of preterm rupture of membranes where measurement of certain amniotic fluid inflammatory markers may be helpful. The ultrasound determines the location of the placenta, fetal position and movements, and characteristics of the amniotic fluid. From the 20 ml of amniotic fluid, the first 2 ml is typically discarded due to mixture with maternal blood cells to ensure high quality fluid sampling. Amniotic fluid can be a rich source of multipotent mesenchymal, hematopoietic, neural, epithelial, and endothelial stem cells. A potential benefit of using amniotic stem cells over those obtained from embryos is that they side-step ethical concerns among anti-abortion activists by obtaining pluripotent lines of undifferentiated cells without harm to a fetus or destruction of an embryo. Artificial heart valves, working tracheas, as well as muscle, fat, bone, heart, neural and liver cells have all been engineered through use of amniotic stem cells.
