Abstract:
OBJECTIVE: Because of the widely origin, easily isolation and cultivation, the powerful multiplication ability and some other characteristics, endothelial progenitor cells have become the most important seeding cells in tissue-engineered vascular, but the condition to become a vascular in vitro, characteristics of endothelial progenitor cells and their progress in research and application in the tissue-engineered vascular deserve further study. DATA SOURCES: A computer-based online search of PUBMED database was undertaken to identify articles about endothelial progenitor cells being seeding cells in tissue-engineered vascular application published from January 1997 to July 2006 by using the keywords of "Endothelial progenitor cells,Tissue-engineered vascular,Tissue Engineering Blood Vessel" in English. STUDY SELECTION: The data were selected firstly, and quotation of each articles were read. Inclusive criteria: all articles related to the characteristics of endothelial progenitor cells and their progress in research and application in the tissue-engineered vascular were selected. Exclusive criteria: repetitive research or Meta articles were excluded. DATA EXTRACTION:Totally 136 articles were collected, of which 30 articles were associated with inclusive criteria. The 106 excluded articles were with old content or repetitive research. The 30 articles contained 8 articles on characteristics of endothelial progenitor cells, 14 articles about the advantages of endothelial progenitor cells as seeding cells in tissue-engineered vascular application, 8 articles on the application of endothelial progenitor cells construction in tissue-engineered vascular. DATA SYNTHESIS: ① Endothelial progenitor cells could be isolated from bone-marrow, peripheral blood, spleen and so on. They expressed CD133 and distinction from endothelial cells by CD133. Endothelial progenitor cells could transform to endothelial cells and smooth muscles, too. ② Endothelial progenitor cells could raise the density of capillary and the number of angiovascular. There were many research indicated that endothelial progenitor cells could improve ischemic, repair the injure of endocardium; Endothelial progenitor cells could improve reendothelialization, protect endomembrane, and hold the integrity of endomembrane; when incorporated with ischemic vascular, endothelial progenitor cells could improve patency rate and prevent restenosis. ③ With smooth muscle cells and some other materials, endothelial progenitor cells could widely applied in constructing tissue-engineered vascular and have a brilliant prospect in the tissue-engineering blood vessel. CONCLUSION: The research of endothelial progenitor cells will have a breakthrough in the expression of its vessel and the function in the organization remodeling. As one of the seeding cells, endothelial progenitor cells have widely origin and the powerful multiplication ability, and they have a brilliant prospect in the tissue-engineering blood vessel.
