University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

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 ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

The miniature models could exponentially accelerate vaccine development, cancer treatment research, and improved health outcomes across a spectrum of diseases. The left image shows the immune organ-on ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...
