Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that ...

Prof Josef Hanna demonstrates the process he and his team of scientists used to develop models of early-stage human embryos without using an egg, sperm or womb, offering a glimpse into the first weeks ...

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, ...

The embryo-like model could help scientists test new drugs, create stem cells for transplants and research blood disorders ...

Researchers have found a new way to produce human blood cells in the lab that mimics the process in natural embryos.
