Abstract: Objective To observe the efficiency of infection of adenovirus containing hepatocyte growth factor(Ad-HGF) on adipose derived stem cells and to prove whether the valid HGF can appear after infection and the multiplicity of infection. Methods We use the digestion separation method and the attachingwall characteristic of the adipose-derived stem cells to separate the human adipose-derived stem cells. Adipose-derived stem cells were infected by the vector of adenovirus (Ad-GFP) which carries the GFP gene,and the GFP acts as the indicating gene to determine the infection efficiency of recombinant adenovirus to adipose- derived stem cells. HGF-ELISA was used to detect HGF as expression-secretion. Results The adherent cells displayed themselves as fibroblast in morphology. The primary cultured cells fusion can arrive to 70% - 80% in 7 - 10 days. The infected HGF can be highly expressed in 48hours. Conclusion Adenovirus can meditate the expression of HGF gene in adipose-derived stem cells effectively.
