Miscarriage risk of amniocentesis is commonly quoted as 0.06% (1:1600). [68] By amniocentesis it is also possible to cryopreserve amniotic stem cells. [69] [70] [71] After 15 weeks
Given the ever-increasing number of elective genetic and genomic tests offered and the wide variety of issues raised by these tests (see pros & cons above), discussion with a clinical geneticist or genetic counselor may be helpful. [56]

The majority of stem cells present in the amniotic fluid share many characteristics, which suggests they may have a common origin. [1]In 2007, it was confirmed that the amniotic fluid contains a heterogeneous mixture of multipotent cells after it was demonstrated that they were able to differentiate into cells from all three germ layers but they could not form teratomas following implantation ...
