Their “programmable” embryo-like structures, also known as embryoids, can be used to study the role of certain genes in early development The earliest days after fertilization, once a sperm cell meets ...

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 ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Disorders/differences of sex development (DSD) are difficult to diagnose because of the multiple phenotypes and genes involved, but a new technique developed at Hudson Institute of Medical Research is ...

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 ...

An unexpected observation has led researchers at the Weizmann Institute of Science to challenge a 200-year-old doctrine regarding the embryonic origins of the pituitary gland. Situated at the base of ...

A molecular pathway known for controlling cell shape and movement also helps regulate the rhythm by which the vertebrate body is divided into repeated segments, FMI researchers report in the journal ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...
