Moreover, it took intensive research work over the past 50 years to identify EPO as the major driver of BM erythropoiesis, purify it from urine derived from patients with aplastic anemia by Goldweisser’s group, clone the EPO gene and produce recombinant EPO, as mentioned earlier [7,8,10,11,12,13]. The gene discussed is EPO; the disease is aplastic anemia.
