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 ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

The early days of how an embryo develops are shrouded in mystery, because it pulls a kind of vanishing act. Once a sperm finds an egg, it begins a roughly weeklong journey to the uterus, becoming a ...

Animal models are established, important tools for preclinical safety and efficacy testing. Companies are advancing more “humanized” models to better reflect human responses, while at the same time ...
