Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

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 ...

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 ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Embedded within the mammalian life cycle is a highly organised progression from fertilisation through preimplantation stages, blastocyst formation, implantation and subsequent axis establishment and ...

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, ...

"Guinea pigs can become a valuable model for understanding how early disturbances in embryonic development can affect health later in life. Since guinea pig development mirrors that of humans better ...
