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 ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide ...

The first organized stem cell culture model that resembles all three sections of the embryonic brain and spinal cord, and produces a full model of the early stages of the human central nervous system, ...

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), ...

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 ...

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 ...

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 ...
