Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...
