The formation of blood vessels is a complex process involving the interplay of proteins and mechanic forces. In two studies, a research team has uncovered new mechanisms in blood vessel formation. The ...

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 ...

Tufts Medical Center and Tufts University scientists have found exciting, new functions of the protein angiogenin (ANG) that play a significant role in the regulation of blood cell formation, ...

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 ...

Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into ...

LMU molecular biologist Gunnar Schotta decodes the epigenetic silencing of problematic retroviral gene sequences. While each cell contains the complete genetic blueprint of an organism, chemical marks ...

The way in which blood stem cells evolve over a lifespan differs greatly between humans and mice, new research reveals. The findings provide a new understanding of the critical factors that influence ...

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, ...
