Development is the process by which a fertilized egg, or embryo, generates the cells, tissues, and organs of a new individual and assembles them into their proper form. Evolution produces the body ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties.

they model embryonic development’s pre-implantation period, up to seven days post fertilization. While stem cell-based embryo models greatly extend the ability to study this period of development, ...

The findings help elucidate what happens during the earliest periods in development. “I was always interested in how cells decide their fate,” Zernicka-Goetz said. In the mouse developing embryo, she ...

Organoids are made to model human organs and are promising for research and therapy, but there are limitations in their growth and function. A recent study found that placenta-derived IL1 under ...

Embryonic stem cells are occupying the minds of most US senators. While it is most pleasing to see cell biology in the limelight, ES cells present the political elite in Washington with one of the ...

Programmable cellular models of embryos, known as embryoids, allow scientists to mimic the first few day of embryonic development. The project team, left to right: Ali Shariati, Sayaka Kozuki, and ...

They targeted regions of the genome known to be involved in the development of an early embryo. This allowed them to control which genes were activated, and induce the creation of the main types ...
