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, ...

Scientists at UCSC used CRISPR technology to create embryo-like structures, or embryoids, from stem cells. These programmable models mimic early developmental stages and allow scientists to study gene ...

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 - ...
