The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined which cells will give rise to which tissues—controlled by epigenetic marks ...

The distinct parental origins of the X chromosome lead to X-specific lower methylation in female embryos (at least in TE lineage), which, combined with the incomplete X chromosome inactivation and sex ...

In August 2022, NIH researchers from the University of Cambridge successfully created a synthetic mouse embryo model using cultured mice stem cells. This project aimed at using stem cells to express ...

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 ...

Building upon previous work, researchers at the Icahn School of Medicine at Mount Sinai identified cells in the embryos of mice that are precursors to blood stem cells or hematopoietic stem/progenitor ...

Using a newly developed method researchers at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) have been able to shed light on the complexity of genome ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

A new study shows that the embryo and the uterine lining conduct an active "conversation" from the very earliest stages of implantation. They engage in a back and forth of tiny packages called ...
