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, ...

Researchers at the Francis Crick Institute have revealed insight into why embryos erase a key epigenetic mark during early ...

Research from Ph.D. candidate Bohan Chen in the lab of Idse Heemskerk of the Department of Cell and Developmental Biology at ...

Tumor cells in colorectal cancer exploit an important signaling pathway that normally controls embryo development.

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

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 ...

The development of the embryo sac continues and proceeds up to about the receptive stage of the stigma. 2. The ovules are cauline, arising from the central axis of the flower. The floral axis bulges ...
