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 ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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, ...

A stem-cell-based monkey embryo model that self-organizes into a comprehensive body plan could lead the way to more-sophisticated models of early human development. Xiangyu Kong is in the Department ...
