About 9% of men of reproductive age in the United States experience fertility problems. One of the many causes of male ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea ...

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human body ...

Humans and sea stars have something in common – here’s why it matters to scientists studying organ development ...

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 ...

Embryonic development in marine invertebrates encompasses a remarkable diversity of reproductive strategies, developmental modes and morphological transitions that underpin the life cycles of major ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

Embryonic development in preimplantation systems encompasses the period from fertilisation through the formation of the blastocyst, during which the zygote undergoes a series of rapid mitotic ...

A recent study delves into the pivotal role of Setd2, a histone methyltransferase enzyme, in embryonic development within mice. Setd2 is instrumental in the trimethylation of histone H3 lysine 36 ...
