Interleukin-1 stimulates prostaglandin biosynthesis by human amnion
A part of the placenta called the amnion
, or the outer membrane of the amniotic sac, routinely discarded "medical waste" may prove to be an abundant source of cells with the same potential to treat diseases and regenerate tissues as embryonic stem cells, according to a new study.
Careful attention should be paid to distinguish the nuchal skin from the amnion
Although chemicals may transfer from mother to fetus via the amniotic fluid after crossing the amnion
, the majority of agents gain access to the conceptus via placental passage (Nau and Liddiard 1978).

Although the cells in amniotic fluid are widely known to have originated from fetal urogenital, respiratory, and alimentary tracts, skin and amnion
, the origin of cell-free fetal DNA in amniotic fluid remains unclear (2).
Placental conditions that have been associated with chorangiosis include umbilical cord anomalies, single umbilical artery, abruptio placentae, placenta previa, chorangioma, amnion
nodosum, and villitis (rubella virus, cytomegalovirus, syphilis, and Bartonella sp are known to infect and induce proliferation of the endothelial cells).
Most are in individual sacs separated by a thin, visible line, which is the amnion
, not the chorion.
