Fig. 4From: ICAM-1-Targeted Liposomes Loaded with Liver X Receptor Agonists Suppress PDGF-Induced Proliferation of Vascular Smooth Muscle Cells a Immunofluorescence images of ICAM-1 expression in MOVAS cells following treatment with platelet-derived growth factor (PDGF)-BB (20 μg/mL) for 24 h. Left column DAPI channel showing blue fluorescence, middle column FITC channel showing green fluorescence from the liposomes, right column DAPI and FITC channels merged. Bars = 50 μm. b Mean FITC fluorescence intensity obtained from images in a. Values are expressed as the means ± SD (n = 3). ***P < 0.01Back to article page
