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 ...

The work appears in Cell. "Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

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 ...

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...
