Abstract: Recently, with the better understanding of the mechanisms of neovascularization, many new therapeutic approaches to enhance neovascularization have emerged. Of these diverse emerging methods, use of growth factors and cells are the two major ones. This review will provide an update on the present understanding of the basic mechanisms of angiogenesis, vasculogenesis, and arteriogenesis, as a basis for designing future pro-neovascularization treatments. Several angiogenic factors including vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) have been implicated in augmenting the neovascularization process. However, single growth factors are not sufficient to generate functional vessels. In synergistic or complementary manner, these factors may be used in harmony to form long-term functional vessels. Cell therapy has the potential to supply stem/progenitor cells and multiple angiogenic factors to the region of ischemia. However, the efficacy of stem cells transplantation may be impaired by low survival rate, insufficient cell number and impaired function in aging and diseases. Combination of cells or cells primed with growth factor(s) or genetic modification may augment the therapeutic efficacy. This paper reviews critical literature in depth to elucidate the mechanism of therapeutic neovascularization, angiogenic factor therapy and cell transplantation. Based on past experience and actual knowledge, we propose future problems and controversies that need to be addressed in order to fully exploit the potential of growth factors and/or cell transplantation with clinical relevance.
