The onset of embryo-specific gene transcription, also known as embryonic genome activation (EGA), is a crucial step in the developmental journey of an organism. Although EGA has been studied to some ...

Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

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 ...

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 ...

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 ...

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 ...

Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development instead of following a fixed program, as reported by researchers from Science ...
