N2 - Restoring blood flow to ischemic tissue is a prerequisite for treatment of ischemic diseases. Cell-based therapy based on bone marrow transplantation is a promising option for patients with critical limb ischemia (CLI). The efficacy of cell therapies to augment neovascularization seems to involve endothelial progenitor cells (EPCs); however, the mechanisms underlying the efficacy have not been fully elucidated. Herein we have described the case of a young patient with severe CLI, who experienced a 24-month beneficial clinical response to autologous bone marrow transplantation. The exceptional amelioration enabled him to perform standardized maximal treadmill exercise test that demonstrated lack of exercise-induced EPC mobilization, despite adequate stromal-derived factor 1 and vascular endothelial growth factor responses. Therefore, tissue ischemia is not sufficient to promote the recruitment of EPCs that have been demonstrated to be involved in the recovery from ischemia. The local implantation of marrow-derived elements may provide cells and/or trophic factors, which have the capacity to augment angiogenesis, opening new approaches to the etiopathogenesis of the disease.
