Lab grown models of embryos, made from clusters of stem cells, are getting increasingly complex. Ethicists, regulators and ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

"Maintaining the egg's naturally quiet metabolism could be a better idea for preserving quality," said molecular biologist Elvan Böke.

Human bodies have to be built from a single egg cell that's fertilized by a sperm cell. Many rounds of cell division occur as the body is developing, and it seems that there are plenty of chances for ...

Some diseases begin in early development. To learn more about how they happen and how they might be treated, and to gain more insight into the basic biology of the human embryo, scientists have to use ...

AP — Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth, and why many pregnancies fail. These models are ...

Scientists have used stem cells to accurately recreate the first stage of human embryo development, in what could be a landmark discovery for research into reproduction. The study – published ...

Introducing the Stem Cell-Based Embryo Lineup One group of researchers sought to determine if human pluripotent cells could aggregate and differentiate into the distinct germ layers—ectoderm, mesoderm ...

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 ...

Researchers construct an embryo-like structure from human stem cells, resulting in a new way to study the earliest stages of development. Research on human embryos is vital to understanding the ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from ...
