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 ...

Researchers uncovered key networks that simultaneously control pluripotency and readiness for cell death (apoptosis), helping to ensure optimal conditions for embryonic development. The study's ...

During implantation, the human embryo is hidden inside a “black box.” Although peeking inside has been prohibited by the 14-day rule, which restricts in vitro studies to preimplantation events, a new ...

At the earliest stages of human embryonic development, a small collection of cells known as human embryonic stem cells (hESCs) orchestrates growth and differentiation, eventually giving rise to highly ...

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 ...

Gene networks in human embryonic stem cells (hESCs) have been found to serve two purposes at once. They maintain pluripotency, and they keep apoptosis, or programmed cell death, on a hair trigger.

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

The maintenance of pluripotency of human embryonic stem cells (hESCs) requires a high efficiency of self-renewal. During in vitro propagation, however, spontaneous differentiation occurs frequently, ...

A team of scientists in the United States and the United Kingdom said they created the world's first synthetic human embryonic structure from stem cells, an advancement that "sidesteps the need for ...
