Embryology is the discipline concerned with the study of embryogenesis, the development of the embryo from a fertilised egg cell. Findings in embryology have helped in the understanding of congenital ...

The use of a precise gene editing technique to edit human embryos has caught the attention of academics and society, yet doubts over its safety and ethics remain. View on euronews ...

A new study has mapped human urogenital development in its native spatial context, revealing how neighboring organs ...

In the normal embryo (left): magenta cells will become the placenta, yellow cells will become the yolk sac, and cyan cells will become the epiblast, which later forms the body. In the embryo where ...

A new study links sperm PLCZ1 mRNA levels to embryo quality in ART, suggesting a dual role for PLCZ1 in fertilization and ...

For the first time, researchers have used a genome editing technique called base editing to identify a master gene that is essential for human embryo development. Marking the first application of base ...

University of Sydney researchers have developed a new way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well, none yet fully ...

Exposure to this flavor in e-cigarettes disrupts early embryonic stem cell development, posing serious potential risks to ...
