Implantation of HGF-modified skeletal myoblasts increase the vessel density.

<p>The Ad-GFP- or Ad-HGF-transduced myoblasts were implanted into the myocardium in an MI model for 28 days. (a) Sections were stained with antibodies against Factor VIII to facilitate the counting of vessels. The representative images of the capillary density in transplanted area were shown. (b) The numbers of vascular densities of groups indicated (n = 6, P<0.05, *P<0.05 <i>vs</i>. SM group; ^#P<0.05 <i>vs</i>. SM-GFP group; ^†P<0.05 <i>vs</i>. control group).
