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 first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

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 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 at the ...

Research improves upon a popular experimental model of mammal development and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo. Research from Ph.D ...

Living structures that model early human embryonic development have been generated entirely from cells in the skin. The models mean it should be possible to study infertility, early miscarriage and ...
