Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

During embryonic development, thousands of cells divide and move collectively to sculpt the main body axes. Understanding the mechanisms that coordinate this collective behavior remains a significant ...

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 ...

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 ...
