A newly created cell model of the amniotic sac could reveal new insights into early pregnancy, as well as generate helpful products for medical use.

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

Listen to more stories on the Noa app. The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a ...

Producing the right number of yolk sac forming cells may be critical for infertility treatment using in vitro fertilised (IVF) embryos. Only limited research can be performed directly on human ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Stem cell biologist Jacob Hanna, a member of the 2024 #STATUSList, predicts human embryo models could pave the way to organ transplants.

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation.

University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells.

Background The yolk sac is a structure observed during the early development of the human embryo that provides nutrients and allows gas exchange to the fetus until the placenta develops fully.

Recent breakthroughs in making stem-cell based human embryo models are raising urgent questions about to what extent they should be treated like natural embryos and whether they are open to misuse.
