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, ...

Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

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 ...

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 ...
