New stem cell model replicates human amniotic sac development

New stem cell model sheds light on human amniotic sac development

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 the first model of amniotic sac development after two weeks.

Stem cells coaxed into most advanced amniotic sacs ever grown in the lab

The sacs grew to roughly 2 centimeters wide and could be used to study early pregnancy. The sacs grew to roughly 2 centimeters wide and could be used to study early pregnancy.

Advanced amniotic sacs created from stem cells

Scientists at the Francis Crick Institute in London have successfully coaxed stem cells into forming fluid-filled amniotic sacs in the lab. The structures, similar in size and composition to those found in a four-week-old pregnancy, mark the most advanced lab-grown amniotic model to date. The findings were published on Thursday (May 15) in the journal Cell. The amnion is a thin membrane that surrounds the embryo and creates the amniotic sac, whi…
