The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

It's one of life's most defining moments - that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage ...

Assistant Professor of Obstetrics and Gynecology, School of Medicine, University of Washington Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a time when embryos are microscopic, fragile, and well out of reach. Until ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Scientists have invented a device that can quickly produce large numbers of living entities that resemble very primitive human embryos. Researchers welcomed the development, described Wednesday in the ...

Stem-cell models provide evidence that viral DNA sequences that entered the human genome in the past were repurposed to aid early stages of embryonic development. Sherif Khodeer is in the Department ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...

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, ...

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 ...
