Gene expression (integrated photon flux) after subcutaneous implantation of lentivirus-delivering (1 × 107 particles) porous PEG hydrogels in the upper back for 8 weeks. * indicates statistically significant difference (p < 0.05) to background levels. # indicates statistically significant difference (p < 0.05) of (3:1) HCNP-functionalized hydrogels to unmodified hydrogels. Doubling and tripling of symbols indicates differences significant at the p < 0.01 and p < 0.001 levels, respectively.
