Healthy red blood cells are puffy with a dimpled middle. “It’s just a really cool shape,” says Velia Fowler, a cell biologist at The Scripps Research Institute in San Diego. For decades, researchers ...

Scientists have developed a way of assessing the ability of red blood cells to deliver oxygen by measuring their shape. This test could improve specialist transplant and transfusion practice as well ...

The genetically modified cells were exposed to erythropoietin (EPO), a hormone that stimulates red blood cell production, and to inflammatory conditions simulating infection. The cells carrying ...
