A new study shows that ultramarathons damage and replenish red blood cells in ways that could help treat cancer patients.

The production of red blood cells from stem cells has emerged as a transformative approach to address chronic blood shortages and meet the increasing demand for transfusion therapies. By harnessing ...

A recent study delves into the science, but doctors say there’s more to it.

What Is a RDW Blood Test? An RDW blood test – also known as a red blood cell distribution width blood test – is a measure of the difference in your red blood cells’ size and volume. RDW is one part of ...

Human bodies make 2 million red blood cells per second. They each live for 120 days and spend that time zooming completely around the body every 20 seconds, carrying oxygen from the lungs to other ...

Scientists have found that a special component in some people's blood provides them with natural protection against malaria. A recent study has demonstrated that a genetic variant named rs112233623-T ...

The amino acid glutamine plays an unexpected role in erythropoiesis, the differentiation of erythroid progenitor cells into mature red blood cells. Ordinarily, glutamine is broken down by stem cells ...

In healthy red blood cells (RBCs), myosin fibers (blue) contract, pulling on actin (pink) and spectrin proteins (purple) connected to the cell membrane and helping to give the cells their distinct, ...

A recent mouse study suggests that low-oxygen conditions, such as being at high altitudes, could cause red blood cells to absorb excess blood glucose, potentially helping to protect against diabetes.
