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 ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

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

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...
