Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique ...

A human embryo ‘base edited’ so that it can’t produce a key protein (right), fails to form the mass of cells that gives rise ...

Altering a single gene in human embryonic cells has revealed that NANOG plays a key role in early embryo development, ...

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 ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by the ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...
