Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

A newly-created mouse-human embryo contains up to 4% human cells — the most human cells yet of any chimera, or an organism made of two different sets of DNA. Surprisingly, those human cells could ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

Genomic scientists have revealed new insights into the process of human embryonic development using large-scale, whole-genome sequencing of cells and tissues from adult humans. The study analyzes ...

Scientists have developed a new model to study an early stage of human development, using human embryonic stem cells. Scientists from the University of Cambridge, in collaboration with the Hubrecht ...

Cambridge University researchers developed the world’s first synthetic human embryo models using stem cells but without using an egg or sperm, which has sparked ethical concerns and questions about ...

A team of researchers in the United States and the United Kingdom says they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm ...

Living structures that model early human embryonic development have been generated entirely from cells in the skin. The models mean it should be possible to study infertility, early miscarriage and ...

Scientists say they could one day help advance the understanding of genetic diseases or the causes of miscarriages Scientists say they could one day help advance the understanding of genetic diseases ...
