The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

The stem cell-based embryo model and actual human embryos share many characteristics but are distinctly different. However, internationally, not everyone agrees on the definitions and what we should ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

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 ...

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 ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

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 ...

University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells.
