The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

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 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 weeks after fertilization. This is ...

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

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 of ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Scientists have invented a device that can quickly produce large numbers of living entities that resemble very primitive human embryos. Researchers welcomed the development, described Wednesday in the ...

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 ...
