A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

A new review from Genes and Diseases sheds light on the pivotal role of LINE-1 elements in preimplantation development and totipotency, revealing their essential contributions to early mammalian ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

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 ...

The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy. It's one of life's most defining moments -- that crucial ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 ...
