The fluid-filled sac that contains and protects a fetus in the womb.
- ‘A part of the placenta called the amnion, or the outer membrane of the amniotic sac, is comprised of cells that have strikingly similar characteristics to embryonic stem cells.’
- ‘Care was exercised not to separate the amniotic sac into its components, the chorion and amnion.’
- ‘Some cells will go to make the baby and the other will be used to make the placenta and amniotic sac.’
- ‘The amniotic sac that contains your baby begins to form about 12 days after conception.’
- ‘The outer cells will go on to form the placenta and amniotic sac that the baby will grow in.’
- ‘Mrs. Marlow's waters had not broken, so Connor was being born inside the amniotic sac.’
- ‘Before a baby is born, it is surrounded by water in the amniotic sac.’
- ‘The doctor can then open the amniotic sac and remove the baby.’
- ‘This means the membranes holding the amniotic sac, which contains your baby and the amniotic fluid, have started to leak.’
- ‘There is a very small glimmer of hope that the amniotic sac will reseal itself and fill back up with fluid.’
