Figure 5From: Anti-inflammatory loaded poly-lactic glycolic acid nanoparticle formulations to enhance myocardial gene transfer: an in-vitro assessment of a drug/gene combination therapeutic approach for direct injection In Vitro Fluorescent Imaging at 48Â hours post transfection. All 4 particle systems exhibited safe and robust uptake in myocytes while not interfering with plasmid uptake and subsequent GFP expression. Yellow signal indicates co-existence of GFP and nanoparticle in: A. PLGA65:35 Aspirin B. PLGA50:50 Aspirin C. PLGA50:50 Prednisolone D. PLGA65:35 Prednisolone.Back to article page
