FIG. 1.

Adenovirus-mediated expression of GFP in hUCMSCs transduced with Ad28.eGFP vector at 3, 5, and 10 days posttransduction. Vertical panels (left to right) represent transient gene expression at days 3, 5, and 10, respectively. Horizontal panels (top to bottom) represent the effect of MOI on the expression level of adenovirally introduced GFP. Note that maximum gene expression was at day 5 and at MOI 100. The figures represent a random microscopy field for one cord. The results were consistent among cords. Scale bar, 100 μm. Color images available online at www.liebertpub.com/cell
