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 ...

This workshop explored the state of the science of mammalian embryo model systems, including nonhuman primate and human models. The goal was to begin with an overview of the developments that have set ...
