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 ...

Stanford has successfully engineered a human uterus lining (endometrium) to be capable of embryo implantation — the first step to creating an artificial womb. On Tuesday, three studies published in ...

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 ...

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 ...

For the first time, scientists have captured a real-time view of a human embryo implanting in a laboratory model of a uterus. Being able to witness the complex implantation process may be helpful for ...

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, bioethicists say that ...
