Pregnancy is a time full of wonder, excitement, and sometimes a bit of worry. The amniotic sac is one of the most fascinating parts of this journey. It is a thin but strong membrane that naturally ...

Researchers have coaxed stem cells to grow into amniotic sacs filled with fluid 1. The model sacs, which grew to roughly the same size as a four-week-old sac surrounding a developing embryo, could be ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

Researchers have made new discoveries about amniotic fluid, a substance historically not well understood in medical research due to the difficulty in obtaining it during pregnancy, especially across ...

The amniotic sac is a fluid-filled, biological balloon that cushions and protects the growing embryo. The liquid it contains is thought to be essential for healthy embryo development. But it hasn't ...

What is low amniotic fluid? Low amniotic fluid (oligohydramnios) is a condition in which the level of amniotic fluid measures lower than expected for a baby's gestational age. Under normal ...

These beautiful pictures show the water birth of baby Juniper, who was born still inside her amniotic sac. She had a water birth in her home helped by her husband, Stephen, their 2-year-old daughter, ...

Many factors, including genetics, stress, and environmental exposure, can shape pregnancy and fetal development. Physicians who care for pregnant patients and their babies before and after birth work ...

An amniotic fluid index measures the amount of amniotic fluid surrounding the baby. It’s an important way for your doctor to assess your baby’s development and identify potential complications. An ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...
