St. Jude Children's Research Hospital scientists have uncovered a regulatory mechanism for signaling of Sonic Hedgehog (SHH), a pathway essential for embryonic development. The findings, published in ...

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 discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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 ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

A study showed that arachidonic acid binds Smoothened to strengthen SHH signaling during heart and lung development.

A new study led by scientists from the Hebrew University of Jerusalem and INSERM identified genes essential for turning embryonic stem cells into brain cells, including a gene linked to a previously ...
