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 ...

Red blood cells, long thought to be passive bystanders in the formation of blood clots, actually play an active role in helping clots contract, according to a new study from researchers at the ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...

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 ...

A new, fast and easy test could revolutionize blood transfusions-giving blood centers and hospitals a reliable way to monitor the quality of red blood cells after they sit for weeks in storage. The ...

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 - ...
