Duration of benefit from stem-cell infusion in anemia typically extends 6–24 months depending on anaemia type and baseline disease severity. Transfusion-independent patients in aplastic anaemia may sustain benefit for 12–36 months; chronic kidney disease patients may require ongoing erythropoietin adjustment over years. Some centres recommend booster infusions at 6–12 month intervals as benefit plateaus. Durability depends on degree of haematopoietic niche reconstitution; patients with persistent bone-marrow suppression experience shorter-duration benefit than those with reversible disease. Long-term freedom from transfusion beyond 5 years post-infusion is inadequately documented.
Anemia encompasses diverse disorders characterised by insufficient red-blood-cell mass or haemoglobin production, ranging from iron deficiency and chronic disease anaemia to haemolytic syndromes and bone-marrow disorders. Stem-cell research investigates whether placental mesenchymal stem cells and fetal stem cells can stimulate erythropoiesis, enhance iron metabolism, reduce chronic inflammation driving anaemia, and regenerate damaged haematopoietic niches. With 531 registered trials — by far the largest evidence base among studied conditions — and 83 currently recruiting, the scope encompasses both direct support of erythroid progenitors and paracrine reduction of inflammatory barriers to red-cell production. The diversity of anaemia aetiologies means that stem-cell approaches must be matched to underlying pathophysiology: supportive in chronic renal disease, immunomodulatory in autoimmune haemolytic anaemia, regenerative in aplastic anaemia.
