Fig. 3. Transduction efficiency for surface and bolus delivery.

Fig. 3

Transduction efficiency for PLG disks (0.32 cm2) coated with collagen (10 μg or 50 μg) or fibronectin (2 μg or 10 μg), with cells infected by bolus delivery (control) or following virus immobilization. Transduction efficiency was calculated by the pixels/mm2. The symbol * and ** indicate statistically significant differences relative to bolus viral delivery group at p < 0.05 and p< 0.01, respectively.
