Other illnesses such as the flu or pneumonia may develop faster than normal because your body cant effectively fight off the infection. Platelets, small blood cell fragments involved in clotting, form from giant marrow cells called megakaryocytes. Normally, when specialized cells in your kidneys detect low blood oxygen levels, they increase the production of EPO. Erythropoietin is a hormone that your kidneys naturally make to stimulate the production of red blood cells. Like mature red blood cells, in mammals, reticulocytes do not have a cell nucleus.They are called reticulocytes because of a . Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment. When an individual joins a bone marrow donation registry, they are agreeing to donate using whichever method the healthcare professional deems appropriate.
