Scientists have engineered an artificial womb lining, a breakthrough allowing unprecedented observation of early human embryo ...

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 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 - ...

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 ...

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 ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it under a microscope. A human blastoid is a stem-cell-made copy of an early ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...
