They mature from reticulocytes.
In glucose-6-phosphate deficiency, these cells lack a semicircular portion and are known as "bite cells." Adhesion in these cells is driven by ICAM-4, or the LW factor. The A1C form of a protein expressed in these cells is measured in a common test for diabetes. These cells have a typical lifespan of 120 days before being destroyed in the (*) spleen. They mature from reticulocytes. These cells completely lack a nucleus, have a bi-concave shape, and can co-dominantly express the A and B antigens on their surfaces. A glutamic acid to valine mutation of a protein in these cells causes them to take a sickle shape. For 10 points, name these cells that carry oxygen and give blood its color.
