Scientists used stem cells to create a model of an embryo in the lab without sperm or egg. The model embryo released the same hormones that trigger positive pregnancy tests. Researchers hope to use ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...

Know how the immune system influences fertility, embryo implantation, and early pregnancy success, with expert insights on ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Smoking in the weeks before and after conception has a potentially unhealthy effect on an embryo, Dutch research shows. "Smoking not only impacts an embryo's growth during pregnancy and birth weight, ...
