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 ...

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 ...

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 ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

Study finds early-stage ectoderm cells are especially susceptible, raising questions about potential developmental risks ...

When the days shorten and the sun sinks low in the sky, that familiar winter slump sets in. There's a fundamental reason for this seasonal fatigue: low levels of vitamin D—the "sunshine vitamin." New ...
