title: [Hepatocyte growth factor recruits endothelial progenitor cells from bone marrow into blood circulation].
abstract: OBJECTIVE
  To assess whether hepatocyte growth factor recruits bone marrow-derived endothelial progenitor cells into blood circulation to participate in postnatal angiogenesis and endothelium repair.
  
  
  METHODS
  The adenovirus vector encoding HGF gene (Ad-HGF) were intravenous administrated into BALB/c mice, and then serum HGF was determined by enzyme-linked immunosorbent assay, the number of CD34+ cells in peripheral blood was assayed by flow cytometry, and the nucleated cells in peripheral blood were isolated, cultured and the endothelial cell colonies were characterized by staining with antibodies against tie-2, vWF. The carbon tetrachloride-induced liver damage model of female mice was established. The peripheral blood nucleated cells of Ad-HGF treated male mice were intravenous administrated into these mice, and 4 weeks later, in situ hybridization for the sry gene was used to identify the implanted cells in the damaged tissues.
  
  
  RESULTS
  Intravenous administration of Ad-HGF resulted in significant elevation of serum hepatocyte growth factor level and induced profoundly increase of endothelial progenitor cells in the peripheral blood, which were characterized by their ability to form endothelial cell colonies in culture and expression of CD34, tie-2, and vW factor. HGF-mobilized endothelial progenitors could incorporate into sites of neovascularization in a liver regeneration model.
  
  
  CONCLUSIONS
  Hepatocyte growth factor could markedly recruit bone marrow-derived endothelial progenitor cells into blood circulation.
