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 ...

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

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

In the earliest stages of life, mammalian embryos start as a disorganized cluster of cells. As development progresses, these cells become organized into well-defined shapes and structures. This ...

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 study published today in the journal Developmental Cell uncovers new insights into how the heart forms during the earliest stages of embryonic development. The research, led by scientists at the ...

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 ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...
