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 have relied on animal models as an alternative to testing on human tissues and cells for decades. But not just any organism can adequately model how human cells behave. Researchers take ...

Researchers at the University of California, Los Angeles (UCLA) have unveiled a novel road map tracking blood stem cell development in the human embryo, findings that could help develop new treatments ...

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 ...

For the first time ever, human patients have received transfusions of blood cells that were grown from stem cells in a lab. A clinical trial investigating the safety of the procedure is currently ...

Blood grown in a laboratory has been transfused into humans for the first time in a landmark clinical trial. Two patients in the U.K. have so far received tiny doses of the lab-grown blood as part of ...

In a groundbreaking achievement, a team of Australian scientists has successfully grown the world’s first fully functioning lab-made human skin that comes with its own blood supply. This breakthrough, ...

We think the human body is fully mapped. In reality, anatomy is still incomplete, and shaped by who was studied, and who wasn ...

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 - ...
