Avian germ cell development stands at the forefront of reproductive and biotechnological research, encapsulating the complex journey of primordial germ cells (PGCs) from early embryogenesis to their ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Pulmonary arterial hypertension (PAH) is a rare condition that's difficult to treat. The hallmarks of the disease—narrowing of the arterioles and capillaries that deliver blood to the lungs—force the ...

Researchers in the College of Agriculture, Health and Natural Resources have developed a novel line of bovine embryonic stem ...

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 ...

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 new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...
