Human red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days. However, is it true for all red blood cells? What are the changes associated with red cell maturation, adulthood and senescence? What are the determinants of red cell life span and clearance? What are the mechanisms in control of red cell mass in healthy humans and patients with various forms of anemia? What are the markers of circulating red cell senescence and in cells during storage and transfusion? Within the life span may properties of red cells change leading to age-mixed circulating cell populations. Although these cells appear to be genetically terminated by the time they are released into the blood stream, they undergo surprisingly versatile modifications depending on the life-style and health conditions of a “human host”. Numerous disorders are believed to be associated with facilitated ageing of red blood cells. “In vitro ageing” and damage of red blood cells during storage is yet one more important issue related to the risks and efficiency of blood transfusion. Many of the mechanisms behind such effects are far from being fully understood. In this context the Research Topic is set to include articles in the field of biochemical investigations, biophysical approaches, physiological and clinical studies related to red blood cell maturation and aging. This includes Original Research, Methods, Hypothesis and Theory, Reviews and Perspectives.

The eBook ‘The red cell life-cycle from erythropoiesis to clearance’ continues the discussion of questions like: What are the changes associated with red blood cell maturation, adulthood and senescence? What are the determinants of red blood cell life span and clearance? What are the mechanisms in control of red blood cell mass in healthy humans and patients with various forms of anaemia? Can red blood cells be 'trained' to provide the body with more oxygen during endurance exercises? What are the markers of circulating red blood cell senescence and in cells during storage and transfusion? And what can be learned from various species that developed advanced adaptations to maintain oxygen delivery under stress conditions such as exercising to the limit, diving or living in anaerobic aquatic habitats or at high altitude? Within the approximately 120 days (or 40 in a mouse, or 150-170 in a horse) life span of 'healthy' red blood cells, many cellular properties change leading to aged mixed cell populations in the circulation. Red blood cells seem to be genetically terminated by the time they become red blood cells and the contributions of this eBook increase the understanding of this process. There are surprisingly versatile remodeling processes happening during the red blood cell life span. Numerous disorders are associated with the premature onset of the 'ageing process' of red blood cells. Furthermore, in vitro ageing and/or modifications as well as the slowing down of the modifications is an important issue in transfusion medicine. Many of the molecular mechanisms behind such effects are elucidated in this eBook.

Anemia in the elderly has been properly defined as the silent epidemic, representing 3 million people in the United States aged 65 years and older. Incidence and prevalence of this condition increase with age. It differs in its etiology, pathogenesis and treatment from anemia in children and younger adults. Anemia is associated with reduced survival, increased risk of functional dependence and hospitalization, increased risk of congestive heart failure and stage renal disease and cognitive disorders. Approximately 70% of anemia in older individuals is reversible.
