Patient discussion about amniotic.

Q. what does it mean when an ultrasound shows an empty amniotic sac and no baby?

A. This exact thing happened with my friend who is now 22 weeks with her first baby. She had 2 additional sacs - both empty - and the doctor said that the pregnancy had probably started out as triplets but that only one of the embryos had actually established and continued to grow.

Her doctor said it is very common for a woman to have more than one egg fertilize but that in most cases the pregnancy continues as a singleton only. She told my friend that the empty sacs would just disappear through time (which they did) and that they posed no danger to her baby.

These stem cells are found in the amniotic fluid of a woman, a substance that is usually discarded upon the birth of a child.
, and his colleagues wondered whether some of the fetal cells in amniotic fluid are stem cells.
