Amnioblast, also known as trophoblast or plasmoblast, is a type of cell found in the amniotic membranes and umbilical cord in humans, and the chorion in other vertebrates. It is an embryonic cell that develops into an outer part of the chorion, which forms the protective outer layer of the fetus.

Amnioblasts are responsible for several important functions. They help in the formation of the amniotic sac and amniotic fluid, which provide protection for the developing fetus. They also supply nutrients to the fetus and help to take away waste products. Finally, amnioblasts secrete hormones that are essential for the proper development of the fetus.

Amnioblast is also involved in the process of placental attachment and implantation in humans. It produces hormones and signals that help the placenta to attach to the inner wall of the uterus. It also produces special proteins that facilitate the attachment.

Amnioblast can be used to produce therapeutic proteins, such as antibodies and cytokines, which can be used to treat a variety of diseases. It can also be used to produce human embryonic stem cells, which can be used in regenerative medicine.

Amnioblasts can also be used to detect Down Syndrome or other chromosomal abnormalities at an early stage of pregnancy. In this process, a small sample of amniotic fluid is taken and tested for the presence of abnormal cells. This can help the doctors to determine whether the fetus is healthy or affected by a genetic disorder.
