Bone marrow cells: Important role on neovascularization of hepatocellular carcinoma.

摘要: Background and Aim:  Present antivascular therapies including embolization to hepatocellular carcinoma (HCC) were not as satisfying expected. The aim was explore whether or bone marrow cells (BMCs) played an important role on neovascularization in HCC. Methods:  Bone marrow-GFP+ orthotropic HCC mice model used. In controls mice, the dynamic change of circulating BMCs serum vascular endothelial growth factor (VEGF), platelet derived (PDGF) measured by flow cytometry enzyme linked immunosorbent assay, respectively. Intrahepatic distribution evaluated using immunofluorescent realtime polymerase chain reaction protocols. BMCs' intrahepatic differentiation proportion vessels investigated methods. Immunohistochemistry western blotting performed examine expression adhesion molecule tumor tissues free tissues. Results:  Compared with controls, frequency VEGF, PDGF much higher mice. number level CD133 gene increased significantly relative zone. Since early stage HCC, have been mobilized, recruited into incorporated different types liver. Besides cells, also differentiated fibroblast hepatic stellate cells. Moreover growth, gradually. Conclusion:  Mobilized vasculogenesis HCC. Combined blockading marrow-mediated may improve efficacy current therapy patients.
