Stem cell-based embryo models (SCBEMs) offer new ways for studying early human development while circumventing ethical challenges associated with natural embryos. Traditionally, SCBEMs are categorised ...

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 structure, from a single starting stem cell population and without direct genetic ...

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 ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by the ...

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 ...

A direct comparison of an embryo (left) and a stem-cell based embryo model representing the embryonic trunk (right). While the example shows a mouse embryo and embryo model, similar embryo models can ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Add Yahoo as a preferred source to see more of our stories on Google. A human embryo model generated from reprogrammed stem cells by the lab of Magdalena Zernicka-Goetz, the Bren professor of biology ...
