Lipid metabolism plays a critical role in red blood cell recovery from acute anemia

Red blood cells are the most abundant cells in the body. It has long been known that when red blood cells break down or anemia occurs due to bleeding, the hormone erythropoietin (EPO) increases, leading to the proliferation of immature cells (erythroblasts) that eventually become red blood cells, thus restoring the red blood cell count.
