Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...

The formation of blood vessels is a complex process involving the interplay of proteins and mechanic forces. In two studies, a research team at the Biozentrum of the University of Basel, Switzerland, ...

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 ...

In mice, blood cell production occurs via strings and clusters of cells within the bone marrow that are responsible for producing specific blood cell types, according to a far-reaching study led by ...

Scientists at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have discovered a previously unknown function of immune cells in the bone marrow. Embryonic macrophages—specialized ...

Scientists have known for years that a lattice of blood vessels nourishes cells in the retina that allow us to see – but it's been a mystery how the intricate structure is created. Now, researchers at ...

Chronic lymphocytic leukemia (CLL) cell–derived exosomes demonstrated the ability to alter healthy donor cell function and suppress normal blood cell formation. These particles affected monocytes, ...

Getting blood from a stone is impossible, but growing blood from 3D mini hearts is now a reality. A research team led by Robert Zweigerdt, a developmental biologist at the Hannover Medical School, ...
