What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

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 ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...

The US biomedical funding agency also hints at future restrictions on research involving human embryonic stem cells.

By Dr. Priyom Bose, Ph.D. A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body (Bb), a remarkable structure that organizes essential molecules to guide ...

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 ...
