Abstract
BACKGROUND Recent studies have suggested that erythropoiesis-stimulating agents (ESAs) may accelerate not only angiogenesis but also vasculogenesis, beyond erythropoiesis. METHODS We conducted a 12-week prospective study in 51 dialysis patients; 13 were treated with recombinant human erythropoietin (EPO, 5290.4 ± 586.9 IU/week), 16 with darbepoetin (DA, 42.9 ± 4.3 µg/week), 12 with epoetin β pegol (CERA, 40.5 ± 4.1 µg/week) and 10 with no ESAs. Vascular mediators comprising endothelial progenitor cells (EPCs), vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2), and high-sensitivity C-reactive protein (hs-CRP) were measured at 0 and 12 weeks. EPCs were measured by flow cytometry as CD45lowCD34+CD133+ cells. RESULTS The EPC count increased significantly to a greater extent in the EPO group than in the other three group, and increased significantly from 0 to 12 weeks in a EPO dose-dependent manner. In both the DA and CERA groups, the EPC count did not change at 12 weeks. Serum levels of VEGF, MMP-2 and hs-CRP were not affected by ESA treatment in all groups. In the CERA group, serum ferritin decreased significantly compared to the no-ESA group and correlated with CERA dose, although use of iron was permitted if required during the prospective study period of 12 weeks. CONCLUSIONS When patients on dialysis were treated with clinical doses of various ESAs, only EPO induced a significant increase of circulating EPCs from bone marrow, whereas, DA and CERA had no effect.

Abstract
Erythropoietin (EPO) is an important hormone responsible for the stimulation of hematopoiesis which is impaired in a variety of diseases, such as chronic kidney disease, cancer chemotherapy, and the use of some anti-HIV drugs. Difficulties in the purification of endogenous EPO due to problems such as technical limitations, heterogeneity of target cells, inadequate amount and immunogenicity of the resultant product, had limited the entry of endogenous EPO in the clinical applications. The integration of medical biotechnology and hematology has introduced novel procedures for the production of human recombinant erythropoietin (rHuEPO), and other erythropoiesis-stimulating agents (ESAs). To investigate and produce rHuEPO, the first step is to recognize the molecular biology and functional pathways, structure, metabolism, and basic physiology of EPO. In this review, all clinical indications, side effects, challenges and notable points regarding EPO, rHuEPO, and other ESAs have also been addressed along with its molecular characterization, such as the modifications needed to optimize their rHuEPO biosynthesis.
