Porous Chitosan Scaffolds with Embedded Hyaluronic Acid/Chitosan/Plasmid-DNA Nanoparticles Encoding TGF-β1 Induce DNA Controlled Release, Transfected Chondrocytes, and Promoted Cell Proliferation
Figure 2
Gel electrophoresis of HA/CS/pTGF-β1 nanoparticles, digests, and control samples.
Lane A shows the DNA molecular weight marker. Lane B shows HA/CS/pTGF-β1 nanoparticles. Lane C shows normal naked pTGF-β1. Lane D shows HA/CS/pTGF-β1 nanoparticles digested by DNase I. Lane E shows naked pTGF-β1 digested by DNase I. Lane F shows HA/CS/pTGF-β1 nanoparticles digested by chitosanase (2.78 µg/µL).
