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 ...

Researchers have identified Nr1h2, a critical transcription factor essential for early embryo development. Their findings enhance our understanding of gene regulation during blastoid formation and ...

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 ...

The International Society for Stem Cell Research (ISSCR) Embryo Models Working Group has released updated recommendations for the oversight and regulation of stem cell-based embryo models (SCBEM), ...

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 ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos heats up.

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 ...

Advances in organoids and embryonic models of human development have the potential to prompt social and existential questions - e.g., what defines human individuality? However, bioethicist Insoo Hyun ...
