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 ...

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 - ...

Our blood consists of many cell types that develop through different stages from a precursor type -- the blood stem cell. An international research team has now investigated the developmental pathways ...

Researchers have found the first direct evidence that tiny particles of air pollution stick to red blood cells, meaning they can travel freely around the body. These particles are produced by vehicle ...

Electrically stimulating key cells in the immune system could "reprogram" them to reduce inflammation and encourage faster and more effective healing in the body. This is the discovery of scientists ...

Experiments in mice reveal an early postnatal window of opportunity for the effective transfer of genes to blood-cell-producing haematopoietic stem cells by injecting mice with gene-carrying ...

Editor’s note: Every year, hundreds of undergraduates at the University of Delaware pursue research under the guidance of a faculty mentor, especially during the summer months. Such experiences ...

There are many ways that the human body responds to stress, from the adrenaline rush of the "fight-or-flight" instinct to more subtle, complex changes that may not be immediately recognizable to us.

Representative light microscopy images of carbonaceous (black) particles adherent to red blood cells (red arrows) from healthy volunteers. Each image is from a different adult volunteer. Researchers ...
