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 human circulatory system shares several fundamental principles with closed-loop fluid transport systems commonly used in industrial applications. In both cases, a pump generates the driving force ...

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production ...

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 - ...

The human blood system is in a constant state of turnover. First-line immune defenders, like neutrophils, need to be replaced after just four to eight hours, platelets can last a week, red blood cells ...

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 ...
